X+ x + 2 + x + 4 = 81 ( the answer is not 25 , 65, or ! )

X + X + 2 + X + 4 = 81

First, combine numbers and Xs.

3x + 6 = 81       -6    -6        3x = 75         X = 25                ← divide by 3 on both sides

It's like discovering the answer to a puzzle. the purpose in solving an equation is to find the value or values of the variable that makes it a true statement. any value of the variable that makes the equation true is called a solution to the equation.
