Give the steps you will use to separate the variables and then solve the equation : 2(y – 1) =8

Answer»

Given 2(y – 1) = 8 

⇒ 2y – 2 = 8 (Distributive property) 

⇒ 2y – 2 + 2 = 8 + 2 (Add 2 on both sides) 

⇒ 2y = 10

⇒ 2y/2 = 10/2 (Divide by 2 on both sides)

⇒ y = 5

Check: 

Substitute y = 5 in the given equation 

LHS = 2(y – 1) 

= 2(5 – 1) 

= 2 × 4 = 8 = RHS 

Hence verified.
