<span>Simplifying
4x + 8y = 30.60
Solving
4x + 8y = 30.60
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-8y' to each side of the equation.
4x + 8y + -8y = 30.60 + -8y
Combine like terms: 8y + -8y = 0
4x + 0 = 30.60 + -8y
4x = 30.60 + -8y
Divide each side by '4'.
x = 7.65 + -2y
Simplifying
x = 7.65 + -2y</span>
