Set up the equation and solve: 13 = 7 + s (next subtract 7 from each side of the equation to solve for s) 6 = s
Set up the equation and solve: x + 5 = -13 (next subtract 5 from each side of the equation to solve for x) x = -18
3h+13 = 7 3h = 7-13 3h = -6 h = -2
1 divided by 13 equals 13

5 it is 5 because 13 + 7 = 20 20 divided by 4 is 5 to find out the answer, work through the equation backwards and use the opposite operations.
Set up the equation and solve: 13 = 7 + s (next subtract 7 from each side of the equation to solve for s) 6 = s
If: 2a+13 = 5a+1 Then: a = 4
Set up the equation and solve: x + 5 = -13 (next subtract 5 from each side of the equation to solve for x) x = -18
3h+13 = 7 3h = 7-13 3h = -6 h = -2
1 divided by 13 equals 13

Solved for y: y=(3x-13)/5 Solved for x: x=(5y+13)/3
13x = 91To solve for x, divide both sides of the equation by 13.13x/13 = 91/13x = 91/13 = 7
-9-2x+x = -13 -2x+x = -13+9 -x = -4 x = 4
