15x-10-6\left(8x-13\right)-13x=16\left(8-3x\right)-62
Use the distributive property to multiply 5 by 3x-2.
15x-10-48x+78-13x=16\left(8-3x\right)-62
Use the distributive property to multiply -6 by 8x-13.
-33x-10+78-13x=16\left(8-3x\right)-62
Combine 15x and -48x to get -33x.
-33x+68-13x=16\left(8-3x\right)-62
Add -10 and 78 to get 68.
-46x+68=16\left(8-3x\right)-62
Combine -33x and -13x to get -46x.
-46x+68=128-48x-62
Use the distributive property to multiply 16 by 8-3x.
-46x+68=66-48x
Subtract 62 from 128 to get 66.
-46x+68+48x=66
Add 48x to both sides.
2x+68=66
Combine -46x and 48x to get 2x.
2x=66-68
Subtract 68 from both sides.
2x=-2
Subtract 68 from 66 to get -2.
x=\frac{-2}{2}
Divide both sides by 2.
x=-1
Divide -2 by 2 to get -1.
