Accerlated 7th Math: Ch. 7 Test Review

6x - 4x + 13x = 0

• x = 0

• x = 1

• x = -1

• x = 15

3x + 12 = 18

• x = 10

• x = 6

• x = 2

• x = -2

x + 4x + 3x = 24

• x = 4

• x = 24

• x = 8

• x = 3

-3.5x - 6.2x = - 87.3

• x = 8

• x = 7

• x = 5

• x = 9

Solve the following equation

9 + 2a = -3 - 4a

• -2

• 2

• 5

• -1

Solve the equation:

3a - 24 = -a

• -8

• 6

• 12

• -12

What is the first step you could take to solve this problem?

1 + 4n - 6n = 1 - 8n

• subtract 8n to both sides

• combine the like terms 4n + -6n

• multiply 6n to both sides

What is the first step you could take?

1 + 4n = 10 - 14n

• Collect the variables (letters) to the left

• subtract 14n to both sides

• add 1 from both sides

• add 10 on both sides

8v - 4(v + 8) = 8

• 2
• 10
• 4
• -4 

Solve the equation:
3(x - 1) = 2x + 9

• x = 12
• X= -12

• x = 10
• x = 6
