Solving Formulas for a Specified Variable

A formula or “literal equation” is a relationship between measurements. Occasionally it is
necessary to take a formula and rearrange it so that it is solved for a different variable.

Examples:
1) Solve for h:

2) Solve for b: P=a+b+c

3) Solve for C:

4) Solve for b:

5) Solve for W: A = 2HW + 2LW + 2LH

6) Solve for h: a(b – h) – hm = r

7) Solve for c: ax – 4c = a(c – d) + 3
