Answer:
Simplifying
3x + 6y = 81
Solving
3x + 6y = 81
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6y' to each side of the equation.
3x + 6y + -6y = 81 + -6y
Combine like terms: 6y + -6y = 0
3x + 0 = 81 + -6y
3x = 81 + -6y
Divide each side by '3'.
x = 27 + -2y
Simplifying
x = 27 + -2y
