One and Two Step Equations

Front

What is a one-step equation?

Back

A one-step equation is an equation that can be solved in a single step by performing the same operation on both sides to isolate the variable.

Front

What is a two-step equation?

Back

A two-step equation is an equation that requires two operations to isolate the variable, typically involving addition or subtraction followed by multiplication or division.

Front

Solve for x: x - 8 = -5

Back

x = 3

Front

Which equation has x=9 as a solution? 4 + x = 12, 5x = 45, 2x = 20, x + 7 = 26

Back

5x = 45

Front

Solve for a: a/3 + 7 = 13

Back

a = 18

Front

Solve for x: (2/3)x - 4 = -10

Back

x = -9

Front

What is the first step to solve the equation x + 5 = 12?

Back

Subtract 5 from both sides to isolate x.

Front

What does it mean to isolate a variable in an equation?

Back

Isolating a variable means to manipulate the equation so that the variable is on one side and all other terms are on the opposite side.

Front

Solve for x: 5x = 45

Back
