Explanation:
We'll be simplifying
7xy + -2x + -2y + 8 = 0
Then reorder the terms
8 + -2x + 7xy + -2y = 0
Solving
8 + -2x + 7xy + -2y = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-8' to each side of the equation.
8 + -2x + 7xy + -8 + -2y = 0 + -8
Reorder the terms:
8 + -8 + -2x + 7xy + -2y = 0 + -8
Combine like terms: 8 + -8 = 0
0 + -2x + 7xy + -2y = 0 + -8
-2x + 7xy + -2y = 0 + -8
Combine like terms: 0 + -8 = -8
-2x + 7xy + -2y = -8
Add '2y' to each side of the equation.
-2x + 7xy + -2y + 2y = -8 + 2y
Combine like terms: -2y + 2y = 0
-2x + 7xy + 0 = -8 + 2y
-2x + 7xy = -8 + 2y
Reorder the terms:
8 + -2x + 7xy + -2y = -8 + 2y + 8 + -2y
Reorder the terms:
8 + -2x + 7xy + -2y = -8 + 8 + 2y + -2y
Combine like terms:
-8 + 8 = 0
8 + -2x + 7xy + -2y = 0 + 2y + -2y
8 + -2x + 7xy + -2y = 2y + -2y
Combine like terms: 2y + -2y = 0
8 + -2x + 7xy + -2y = 0
