Step 1: Simplify both sides of the equation.

- (5 - (a+1)) = 9 - (5 - (2a-3))

- (5 - (a+1)) = 9+-1 (5 - (2a-3)) (Distribute the Negative Sign) - (5 - (a+1)) = 9 + (-1) (5) + - 1 (-2a) + (-1) (3) - (5 - (a+1)) = 9+-5+2a+-3 a+-4=9+-5+2a+-3 (Distribute) a-4 = (2a) + (9+-5+-3) (Combine Like Terms) a-4=2a+1 a-4=2a+1 Step 2: Subtract 2a from both sides. a-4-2a=2a+1-2a - a-4=1 Step 3: Add 4 to both sides. - a-4+4=1+4 - a=5 Step 4: Divide both sides by - 1. - a-1=5-1 a=-5
