4x+2-3\left(3x-5\right)=4\left(x-5\right)-8
Use the distributive property to multiply 2 by 2x+1.
4x+2-9x+15=4\left(x-5\right)-8
Use the distributive property to multiply -3 by 3x-5.
-5x+2+15=4\left(x-5\right)-8
Combine 4x and -9x to get -5x.
-5x+17=4\left(x-5\right)-8
Add 2 and 15 to get 17.
-5x+17=4x-20-8
Use the distributive property to multiply 4 by x-5.
-5x+17=4x-28
Subtract 8 from -20 to get -28.
-5x+17-4x=-28
Subtract 4x from both sides.
-9x+17=-28
Combine -5x and -4x to get -9x.
-9x=-28-17
Subtract 17 from both sides.
-9x=-45
Subtract 17 from -28 to get -45.
x=\frac{-45}{-9}
Divide both sides by -9.
x=5
Divide -45 by -9 to get 5.
