3x+15-2\left(3+x\right)-5x=13+4\left(x-1\right)
Use the distributive property to multiply 3 by x+5.
3x+15-6-2x-5x=13+4\left(x-1\right)
Use the distributive property to multiply -2 by 3+x.
3x+9-2x-5x=13+4\left(x-1\right)
Subtract 6 from 15 to get 9.
x+9-5x=13+4\left(x-1\right)
Combine 3x and -2x to get x.
-4x+9=13+4\left(x-1\right)
Combine x and -5x to get -4x.
-4x+9=13+4x-4
Use the distributive property to multiply 4 by x-1.
-4x+9=9+4x
Subtract 4 from 13 to get 9.
-4x+9-4x=9
Subtract 4x from both sides.
-8x+9=9
Combine -4x and -4x to get -8x.
-8x=9-9
Subtract 9 from both sides.
-8x=0
Subtract 9 from 9 to get 0.
x=0
Product of two numbers is equal to 0 if at least one of them is 0. Since -8 is not equal to 0, x must be equal to 0.
