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 in solving the equation: 5x + 7 = 12?

Back

Subtract 7 from both sides to isolate the term with the variable.

Front

Solve for a: -5 - 6a = -59

Back

a = 9

Front

What is the solution to the equation: 9 = 4g + 13?

Back

g = -1

Front

Solve for b: -12 = 24 + 4b

Back

b = -9

Front

What is the first step in solving the equation: -5 + 7k = -19?

Back

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

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

What operation would you perform first in the equation: 3x - 4 = 11?

Back

Add 4 to both sides.

Front

What is the solution to the equation: 2x + 3 = 11?

Back

x = 4

Front

How do you check your solution for an equation?

Back

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