Respuesta :

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.

Hope it helped,
