Question

A) Rearrange the following formula to make x the subject.

Give your answer in its simplest form.
4(2x - 3y) = y + 5
+

Answer 1

x = 13y + 0.625

Explanation:

4(2x - 3y) = y + 5

8x - 12y = y + 5

8x = y + 5 + 12y

8x = 5 + 13y

8x ÷ 8 = 5 + 13y ÷ 8

x = 5 + 13y ÷ 8

x= 13y + 5 ÷8

x = 13y + 0.625
