Example 1
The volume V of a rectangular box is given by the formula V = lwh where l is length, w width, and h height. What is the height of a rectangular box with volume 56 cm3, length 4 cm, and width 2 cm?
Example 2
Solve the formula 8x + 4y = 12 for y.
Example 3
Solve the formula z3 – 3x + z2 = z for x.
Example 4
If 4x – y = 5, find x when y = 15.
Example 5
If y2 + 2y – 3x = 5, find x when y = 2.
