Solving 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.

Front

What is the first step to solve the equation -6x + 1 = -11?

Back

Subtract 1 from both sides to isolate the term with the variable.

Front

What is the second step to solve the equation -6x + 1 = -11 after isolating the variable term?

Back

Divide both sides by -6 to solve for x.

Front

Solve for x: 9 = 4g + 13

Back

g = -1

Front

What is the process to solve the equation 8 - 2x = 30?

Back

First, subtract 8 from both sides, then divide by -2.

Front

Solve for x: -12 = 24 + 4b

Back

b = -9

Front

What is the first step to solve the equation -5 + 7k = -19?

Back

Add 5 to both sides to isolate the term with the variable.

Front

Solve for k: -5 + 7k = -19

Back

k = -2

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 by itself.

Front

What is the importance of performing the same operation on both sides of an equation?

Back

It maintains the equality of the equation.
