13x = 91To solve for x, divide both sides of the equation by 13.13x/13 = 91/13x = 91/13 = 7
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

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

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.
To solve the equation 1 + 2x + 13 = 9, you first need to simplify by combining like terms. Subtract 1 and 13 from both sides of the equation to isolate the variable term. This gives you 2x = -5. Finally, divide by 2 on both sides to solve for x, which gives you x = -5/2 or -2.5.
