You can solve this by combining the like terms on one side of the equation.
x=8+5
x=13
You can check to see if the answer is true by substituting 13 for x in the equation.
13=8+5
13=13
Equation step-bystep:
x = 8 + 5 → We sum 8 + 5
x = 13
Proof:
13 = 8 + 5 → We subsitute the x's by 13
13 = 13 → If both numbers are the same, the equation is correct.
