• Line 3 - You should have multiplied  2 on both sides.
• Line 3 - Calculation error
• There are no mistakes.

What is the inverse operation of multiplication? 

• multiplication
• addition
• subtraction 
• division 

 What is the first step in solving the following equation?
4(x + 6) = 40

• Subtract 6 from both sides
• Multiply the variable and constant in the parenthesis by 4
• Divide the variable and constant in the parenthesis by 4
• add 6 to both sides

 What is the solution for the following equation?
4(x + 6) = 40

• x = 4
• x = 6
• x = 8
• x = 12

18 = 3(x + 3)

• x = 1/2
• x = 7/2
• x = 3
• x = 5

3y + 4y + 6 = 20

• y = 2
• y = -2
• y = 4
• y = 3

 6(x + 10) = 63

• x = 1/2
• x = 7/2
• x = 3
• x = 5

2y + 5 + 2y - 1 = 8

• y = 1
• y = -8
• y = -1
• y = 7
