Solve for x. -1/2 (x+5)=2x -3/2
Amiraneli [1.4K]

Start from

-\dfrac{1}{2}(x+5)=2x -\dfrac{3}{2}

It may be useful to multiply the whole expression by 2, in order to get rid of denominators:

-(x+5)=4x -3

Distribute the negative sign in the left hand side:

-x-5=4x -3

Move all terms involving x to the left, and all constants to the right:

-x-4x=-3+5

Sum like terms:

-5x=2

DIvide both sides -5:

x = -\dfrac{2}{5}
