4y = -y +5(x-2) -10z

Instead of the more traditional approaches of solving with respect to a variable, solve it with respect to 5. Prove your answer is correct by using substitution with your answer into the number 6.

E.g. since 5 + 5/5 = 6 then
Solution for 5 + solution for 5 ÷ 5
Should equal solution for 5 + 1
