Answer:
2x + y = 14
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-1y' to each side of the equation.
2x + y + -1y = 14 + -1y
Combine like terms: y + -1y = 0
2x + 0 = 14 + -1y
2x = 14 + -1y
Divide each side by '2'.
x = 7 + -0.5y
Simplifying
x = 7 + -0.5y
