Solve the formula for the indicated variable

1. Solve for b:

A = 1/2 bh

2. Solve for C:

F = 9/5 C + 32

1. first multiply both sides by 2 to get rid of the fraction

2A = bh

then divide both sides by h to get b alone

2A/h = b

2.

subtract 32 from both sides to get C alone

F - 32 = 9/5C

Multiply both sides by 5 to get rid of the fraction

5F - 160 = 9C

To get just C, divide both sides by 9

5F-160/9 = C
