In the equation 4y - 9 = -36

• True

• False

-4x+1=21

• x=120

• x=5

• x=30

• x=-5

15 = 2a + 7

• 2

• 4

• 12

• 14

Where/what is the mistake?

• Line 2 - You should add 12 to both sides.

• Line 4 - You should divide both sides by 2/3.

• Line 4 - You should multiply both sides by the original fraction.

• Line 5 - There was a calculation error.

• 4 ¾
• 3 ⅓
• 5 ⅜
• 3 ⅙
