Write and solve an equation for the problem below. Check the question AND the answer.

Kathy bought some books for her book store for $12 each. She received $35 off her entire purchase and spent a total of $685.

• 12x+35=685

• 12x-35=685

• -12x+35=685

• x=35

• x=60

Solve: \(5=4a-7\)

• a = -3

• a = 3

• a = -2

• a = 2

What is the first step for solving the Equation 16 = 5x - 9 ?

• Subtract 16 from both sides

• Subtract 9 from both sides

• Add 9 to both sides

• Add 16 to both sides

To solve equations, we use "Inverse" or "Opposite" operations

• TRUE

• FALSE

-5 - 6a = -59

• a= 11

• a= -6

• a= 9

• a= 2

-12 = 24 + 4b

• 3

• 0

• -9

• 9
