C1 One-Step Equations and Models

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 does it mean to isolate a variable in an equation?

Back

Isolating a variable means to get the variable alone on one side of the equation, making it easier to find its value.

Front

Solve for x: -6 + x = -14

Back

x = -8

Front

Solve for x: 3x = 126

Back

x = 42

Front

Back

x = -100

Front

Solve for x: -15 + x = 25

Back

x = 40

Front

Solve for x: -8x = 128

Back

x = -16

Front

What is the first step to solve the equation -6 + x = -14?

Back

Add 6 to both sides of the equation.

Front

What operation would you use to solve 3x = 126?

Back

Divide both sides by 3.

Front

Back

It represents that x divided by -5 equals 20.
