1Which step in solving this equation is justified by the ssociative Property of Addition? Consider the sequence of steps to solve the equation: 6v+3(7-5)= 4v - (2v + 1) Given =6y + 3(-5) = 4v - (2y + 1) Step 1 = 6 + 3y - 15 = 4y - (2) + 1) Step 2 => 6v + 3y - 15 = 4y = 2y + 1 Step 3 => 9v - 15 = 4v - 2y = 1 Step 4 => 9v - 15 =- 2y + 4y - 1 Step 5 => 9 = 19 = 2y = 1 Step 6 7 15 = 1 Step 7 = ?v = 14 Step 8 =>= 2
