Tamara is 3 times Kim's height less 4 inches. Tamara and Kim have a combined height of 92 inches. How many inches tall is Tamara?
Let's be accurate as possible and think first.
68
Let K = Kim's height.

Tamara = 3K - 4.

K + 3K - 4 = 92.

4K - 4 = 92.

4K = 96.

Kim = 24 inches.

Tamara = (3 * 24) - 4 = 68 inches.

Tamara is 68 inches tall.
