5+2x+8 To solve for x, we can first set this expression equal to 0. Doing this makes the expression a solvable equation. 5+2x+8=0 Add 5 and 8. 13+2x=0 Then, subtract 13 so that the x is on one side of the equation. 2x=-13 Dive both sides of the equation by 2 to get x by itself. 2x/2=-13/2 That gives us... x=-13/2 You can use long division to divide this fraction out if a decimal answer is needed.
12x + 5 - 2x =(12x - 2x) + 5 =10x + 5 =5 (2x + 1)
