## What are the four basic rules of algebra?

Basic Rules and Properties of AlgebraCommutative Property of Addition.

a + b = b + a.

Examples: real numbers.

…

Commutative Property of Multiplication.

a × b = b × a.

Examples: real numbers.

…

Associative Property of Addition.

(a + b) + c = a + (b + c) Examples: real numbers.

…

Associative Property of Multiplication.

(a × b) × c = a × (b × c) Examples: real numbers..

## What are the four rules of algebra?

The Basic Laws of Algebra are the associative, commutative and distributive laws. They help explain the relationship between number operations and lend towards simplifying equations or solving them.

## What is a 2 step equation example?

Example: In the equation 3x – 2 = 16, notice that the variable is being multiplied and has a term being subtracted. To isolate the variable, we need to add 2 to both sides and then divide both sides by 3.

## What are the steps to solving an equation?

A General Rule for Solving EquationsSimplify each side of the equation by removing parentheses and combining like terms.Use addition or subtraction to isolate the variable term on one side of the equation.Use multiplication or division to solve for the variable.

## What are the four steps to solve multi step equations?

This concept of performing the same operation in both sides applies to the four arithmetic operations, namely: addition, subtraction, multiplication, and division. For example, if we add 5 on the left side of the equation we must also add 5 on the right side.

## What are 2 step equations?

1) First, add or subtract both sides of the linear equation by the same number. 2) Secondly, multiply or divide both sides of the linear equation by the same number. 3)* Instead of step #2, always multiply both sides of the equation by the reciprocal of the coefficient of the variable.

## How do you solve multi step problems?

Here are steps to solving a multi-step problem: Step 1: Circle and underline. Circle only the necessary information and underline what ultimately needs to be figured out. Step 2: Figure out the first step/problem in the paragraph and solve it. Last step: Find the answer by using the information from Steps 1 and 2.

## How do I simplify an expression?

Here are the basic steps to follow to simplify an algebraic expression:remove parentheses by multiplying factors.use exponent rules to remove parentheses in terms with exponents.combine like terms by adding coefficients.combine the constants.

## What is the golden rule for solving equations?

Do unto one side of the equation, what you do to the other! When solving math equations, we must always keep the ‘scale’ (or equation) balanced so that both sides are ALWAYS equal.

## How do you solve an equation with two variables?

In a two-variable problem rewrite the equations so that when the equations are added, one of the variables is eliminated, and then solve for the remaining variable. Step 1: Multiply equation (1) by -5 and add it to equation (2) to form equation (3) with just one variable.

## How do you solve 3 equations with 3 variables?

Here, in step format, is how to solve a system with three equations and three variables:Pick any two pairs of equations from the system.Eliminate the same variable from each pair using the Addition/Subtraction method.Solve the system of the two new equations using the Addition/Subtraction method.More items…

## What comes first in solving equations?

In mathematics, the order of operations define the priority in which complex equations are solved. The top priority is your parenthesis, then exponents, followed by multiplication and division, and finally addition and subtraction (PEMDAS).
