Answer:
Explanation:
Simplifying
7x + 2y = 180
Solving
7x + 2y = 180
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
7x + 2y + -2y = 180 + -2y
Combine like terms: 2y + -2y = 0
7x + 0 = 180 + -2y
7x = 180 + -2y
Divide each side by '7'.
x = 25.71428571 + -0.2857142857y
Simplifying
x = 25.71428571 + -0.2857142857y
