5\left(x-1\right)=3x-15
Multiply both sides of the equation by 3.
5x-5=3x-15
Use the distributive property to multiply 5 by x-1.
5x-5-3x=-15
Subtract 3x from both sides.
2x-5=-15
Combine 5x and -3x to get 2x.
2x=-15+5
Add 5 to both sides.
2x=-10
Add -15 and 5 to get -10.
x=\frac{-10}{2}
Divide both sides by 2.
x=-5
Divide -10 by 2 to get -5.
