Solve for x:

-16 + 7n + n = 8n + 4n

• -4

• -14

• -16

• 11

What is the first step to solve this equation?
3x + 6 = 10 + 3x + 4x

• Add 4x to both sides of the equation

• Combine like terms 3x and 4x on the same side of the equation

• Add 3x and 6 to get 9x

• Add 6 and 10 to get 16

Solve for x:

-6(2v + 4) = -8(v - 4)

• -8

• -13

• -14

• 14

Solve for f:
f - 4 = 6f + 26

• f = -5

• f = 5

• f = 6

• f = -6

Solve the equation
4x - 5x + 9 =5x - 9

• x = -3

• x = 9

• x = 3

• x = -9

6x - 4 = 8x

• 2

• -2

• 3

• 0

8 - 9t = 21t - 17

• t = 6/5

• t = 5/6

• t = 1

What is v?
-15v-40 = 23-8v

• v = 9

• v = -7

• v = -9
