-3x-2\left(x-1\right)=5
Multiply both sides of the equation by 6, the least common multiple of 2,3,6.
-3x-2x+2=5
Use the distributive property to multiply -2 by x-1.
-5x+2=5
Combine -3x and -2x to get -5x.
-5x=5-2
Subtract 2 from both sides.
-5x=3
Subtract 2 from 5 to get 3.
x=\frac{3}{-5}
Divide both sides by -5.
x=-\frac{3}{5}
Fraction \frac{3}{-5} can be rewritten as -\frac{3}{5} by extracting the negative sign.
