3x-9=5x-4+3\left(7-x\right)
Use the distributive property to multiply 3 by x-3.
3x-9=5x-4+21-3x
Use the distributive property to multiply 3 by 7-x.
3x-9=5x+17-3x
Add -4 and 21 to get 17.
3x-9=2x+17
Combine 5x and -3x to get 2x.
3x-9-2x=17
Subtract 2x from both sides.
x-9=17
Combine 3x and -2x to get x.
x=17+9
Add 9 to both sides.
x=26
Add 17 and 9 to get 26.
