Isolate the variable to get x=-4.

Explanation:

First we'd want to isolate the variable, x, on the left side of the equal sign.

Subtract the 2x on both sides, so we now have 2x+3=-5.

Subtract the 3 from both sides, so we now have 2x=-8.

Continue to isolate our x by dividing by two on both sides.

(2x)/2=-8/2

x=-4.
