6x-8+5\left(6x-7\right)-7x=16\left(x+15\right)-10
Use the distributive property to multiply 2 by 3x-4.
6x-8+30x-35-7x=16\left(x+15\right)-10
Use the distributive property to multiply 5 by 6x-7.
36x-8-35-7x=16\left(x+15\right)-10
Combine 6x and 30x to get 36x.
36x-43-7x=16\left(x+15\right)-10
Subtract 35 from -8 to get -43.
29x-43=16\left(x+15\right)-10
Combine 36x and -7x to get 29x.
29x-43=16x+240-10
Use the distributive property to multiply 16 by x+15.
29x-43=16x+230
Subtract 10 from 240 to get 230.
29x-43-16x=230
Subtract 16x from both sides.
13x-43=230
Combine 29x and -16x to get 13x.
13x=230+43
Add 43 to both sides.
13x=273
Add 230 and 43 to get 273.
x=\frac{273}{13}
Divide both sides by 13.
x=21
Divide 273 by 13 to get 21.
