-2-3x=3\left(-5\right)x+8
Multiply both sides of the equation by 12, the least common multiple of 6,4,3.
-2-3x=-15x+8
Multiply 3 and -5 to get -15.
-2-3x+15x=8
Add 15x to both sides.
-2+12x=8
Combine -3x and 15x to get 12x.
12x=8+2
Add 2 to both sides.
12x=10
Add 8 and 2 to get 10.
x=\frac{10}{12}
Divide both sides by 12.
x=\frac{5}{6}
Reduce the fraction \frac{10}{12} to lowest terms by extracting and canceling out 2.
