6x+42-2\times 8x=17-3\times 5x
Multiply both sides of the equation by 6, the least common multiple of 3,6,2.
6x+42-16x=17-3\times 5x
Multiply -2 and 8 to get -16.
-10x+42=17-3\times 5x
Combine 6x and -16x to get -10x.
-10x+42=17-15x
Multiply -3 and 5 to get -15.
-10x+42+15x=17
Add 15x to both sides.
5x+42=17
Combine -10x and 15x to get 5x.
5x=17-42
Subtract 42 from both sides.
5x=-25
Subtract 42 from 17 to get -25.
x=\frac{-25}{5}
Divide both sides by 5.
x=-5
Divide -25 by 5 to get -5.
