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
