8v - 4(v + 8) = 8

• 2

• 10

• 4

• -4 

-(n - 8) = -2

• 6

• 10

• -10

• -6

Solve the equation:

2(x + 3) = 8

• 2.5

• 1

• 7

• 5.5

Solve 2x - 3 = 1 

• 3

• 2

• 1

• -2

Solve: 5x + 15 = 10x - 40

• x = 10

• x = -10

• x = 11

• x = -11

Solve: 12x + 1 = 6x - 47

• x = 6

• x = -7

• x = -8

• x = 9

3x - 32 = -7x + 28

• x = 6

• x = -6

• x = 1/6

• x = -1/6

ax + c = R
(solve for x) 

• ax = R + c

• ax = R - c

• x = a(R-c)

• x = (R-c) / a 

S = 3F - 24  Solve for F

• F = (S + 24)/3

• F = S/3 + 24

• F = 3S + 24

• F = 3(S + 24)

a = b + c   , for  c

• c = a - b

• c = a + b

• c = ab

• c = a / b
