Dox needs to solve the system of equations below. 4x + 5y = 7 2x – 3y = 9 He decides to use the elimination method to cancel out the x terms in order to first solve for y. Dox uses the following steps: Step 1: 4x + 5y = 7 -2(2x) - 3y = 9 Step 2: 4x + 5y = 7 -4x - 3y = 9 Step 3: 2y = 16 Step 4: y = 8 Did Dox use the correct steps to solve for y?
