Solve -2 = 4r + s for s.

• s = -2 + 4r
• s = 2 - 4r
• s = -2 - 4r
• s = 2 + 4r

Solve for x:

• x = yb - v
• x = by - v
• x = by + v

Solve for n:
2m - n = 8

• n = 2m - 8
• n = -2m - 8
• n = 2m + 8
• n = -2m + 8

Solve for x: u = 2x - 2

Solve for a:            12am = 4

• a = 4 -12m

• a = ukb

• a = uk + b

• k = 24-x

2.  Given 15x + 1 = y, solve for x.
