Aliyah had $24 to spend on seven pencils. After buying them she had $10. How much did each pencil cost?

• 24-10=7x

• 7x- 24=10

• 7x+ 10=24

• 10+x=14

• x = 4

• x = 5

• x = 3

• x = -2

50 = 28.1 + 0.15a

• a= 150

• a= 146

• a= 6

What is the first step in solving the following equation?
3x - 5 = 20

• multiply both sides by 5

• add 5 to both sides

• divide both sides by 5

• subtract both sides by 5

Solve for x:

• x = 20

• x = 7

• x = 10

• x = 3

If the coefficient of the variable is a fraction, dividing both sides by a fraction is the same as...

• dividing by a whole number

• subtracting the fraction

• using order of operations

• multiplying by the reciprocal
