Checkpoint - 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 m: m + 12 = 10

Back

m = -2

Front

Solve for g: -2 = g - 9

Back

g = 7

Front

What does it mean to isolate a variable?

Back

To isolate a variable means to manipulate the equation so that the variable is on one side of the equation by itself.

Front

What is the first step to solve the equation x - 5 = 10?

Back

Add 5 to both sides of the equation.

Front

What is the solution to the equation 3x = 12?

Back

x = 4

Front

How do you check if your solution is correct?

Back

Substitute the solution back into the original equation to see if both sides are equal.

Front

What is the inverse operation of addition?

Back

Subtraction is the inverse operation of addition.

Front

What is the inverse operation of multiplication?

Back

Division is the inverse operation of multiplication.
