2 (2x + 3) = -6 (x + 9)

• x = 4

• x = 6

• x = -6

• x = -2

Solve for x:

4x - 7 = 21

• x = 28

• x = 7

• x = 21

• x = 4

What is the first step to solve this equation?

-3x + 11 = 44

• Add 3 to both sides.

• Subtract 11 from both sides.

• Subtract 11x from both sides.

• Add 3 to both sides.

Solve for k:

2k + 12 = -4

• k = -8

• k = -4

• k = -16

• k = 4

• Add 6 to both sides.

• Subtract 10 to both sides.

• Subtract 8x to both sides.

• x = 2

Solve for n:

7 (1 + 2n) = -105

• n = -7

• n = 7

• n = -8

• n = 8

Solve for r:

-87 = -3 (3r + 8)

• r = 8

• r = 7

• r = -63

• r = -7

Solve for v:

8v - 4 (v + 8) = 8

• v = 3

• v = 10

• v = 6

• v = -6

Solve for x:

2x - 3 + 4x = 27

• x = 12

• x = 4

• x = 5
