The answer is x= 20.
Plug 8 in for y and then add 2 to both sides. You'll get 10= 1/2x so divide both sides by 1/2 to get your answer of 20.

Constant: A value that doesn't change. Instead, it's a fixed value.
Variable: A symbol (usually a letter) standing in for an unknown numerical value in an equation.
Term: Either a single number or variable, or numbers and variables multiplied together. (Terms are separated by + or − signs, or sometimes by divide.)
