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

• 24-10=7x

• 24+7x=10

• 10+7x=24

• 10+x=14

x / 7  + 14 = 22

• x = -56
• x = 56
• x = -9
• x = 9

• x= 2
• x= -2
• x= 3
• x= -3

7w + 3 = 5w + 9

• w = 25

• w = 3

• w = 14

• w = 10

y ⁄ -8 > 2 

• y < -16
• y > -16
• y < -0.25
• y > -0.25

• x > -7

• x < -7
