8x-144=3\left(3x-5\right)
Use the distributive property to multiply 2 by 4x-72.
8x-144=9x-15
Use the distributive property to multiply 3 by 3x-5.
8x-144-9x=-15
Subtract 9x from both sides.
-x-144=-15
Combine 8x and -9x to get -x.
-x=-15+144
Add 144 to both sides.
-x=129
Add -15 and 144 to get 129.
x=-129
Multiply both sides by -1.
