Back

a = -8

Front

Solve for x: 2x + 17 = -23

Back

x = -20

Front

Solve for x: -4x + 1 = 21

Back

x = -5

Front

Solve for c: 3c + 5 = 23

Back

c = 6

Front

What is the first step in solving the equation 5b - 6 = 24?

Back

Add 6 to both sides.

Front

What is the second step in solving the equation 5b - 6 = 24?

Back

Divide both sides by 5.

Front

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

Back

Isolating the 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 is the purpose of performing the same operation on both sides of an equation?

Back

To maintain the equality of the equation.

Front

If you have the equation 4x - 8 = 0, what is the first step to solve for x?
