12.10.24 Per 8 Review Two-Step Equations

Front

What is a two-step equation?

Back

A two-step equation is an algebraic equation that requires two operations to solve for the variable. For example, in the equation 3x - 2 = 4, you would first add 2 to both sides and then divide by 3.

Front

Solve for x: 3x - 2 = -29

Back

x = -9

What is the first step to solve the equation 3n - 15 = 12?

Back

Add 15 to both sides.

Front

Back

w = -4

Front

What do you do after isolating the variable term in a two-step equation?

Back

You perform the inverse operation to solve for the variable.

Front

Solve for x: 7x - 12 = 37

Back

x = 7

Front

What is the purpose of showing work when solving equations?

Back

Showing work helps to track the steps taken to arrive at the solution and ensures accuracy.

Back

Divide by 7 on both sides.

Front

Define 'inverse operation' in the context of solving equations.

Back

An inverse operation is an operation that reverses the effect of another operation, such as addition and subtraction or multiplication and division.
