Answer:
Simplifying
4x + -5y + -8 = 7
Reorder the terms:
-8 + 4x + -5y = 7
Solving
-8 + 4x + -5y = 7
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 + 4x + 8 + -5y = 7 + 8
Reorder the terms:
-8 + 8 + 4x + -5y = 7 + 8
Combine like terms: -8 + 8 = 0
0 + 4x + -5y = 7 + 8
4x + -5y = 7 + 8
Combine like terms: 7 + 8 = 15
4x + -5y = 15
Add '5y' to each side of the equation.
4x + -5y + 5y = 15 + 5y
Combine like terms: -5y + 5y = 0
4x + 0 = 15 + 5y
4x = 15 + 5y
Divide each side by '4'.
x = 3.75 + 1.25y
Simplifying
x = 3.75 + 1.25y
