Solve the following equation and check your answer: 2(3y - 2) - 4(2y - 5) = 9

Question

KnowledgeBoat · Accepted Answer

We have: 2(3y - 2) - 4(2y - 5) = 9 ⇒ 6y - 4 - 8y + 20 = 9 [Removing brackets] ⇒ -2y + 16 = 9 ⇒ -2y = 9 - 16 [Transposing +16 to RHS] ⇒ -2y = -7 ⇒ y = ∴ y = Check: LHS = 2(3y - 2) - 4(2y - 5) = - = - 4(2) = 17 - 8 = 9 RHS = 9 Hence, LHS = RHS.
