He would have to sale $500,000
9% of $500,000 is $45,000
So $30,000 plus $45,000 is $75,000

Just simply add 6 to both sides, it will cancel out the -6 and leave T alone, and it will become T=2, There's your answer.
3-4z=-5+8z
Add 5 to both sides
8-4z=8z
Add 4z to both sides
8=12z
Divide both sides by 12
z=12/8
Simplify
z=3/2
