Make y the subject means to manipulate the expression such that you get y = ______
A = r(y + 2)/5
Step① : Multiply both sides by 5 to get rid of the denominator
5 x A = 5 x r(y + 2)/5
5A = r(y + 2)
Step ② : divide both sides by r
5A ÷ r = r(y + 2) ÷ r
5A / r = y + 2
Step ③ : subtract 2 from both sides
5A/r - 2 = y + 2 - 2
5A/r - 2 = y
Rewrite as y = 5A/r - 2
(Done)
