Answer:
x = 3.5y
Step-by-step explanation:
Simplifying
3x + 8y + -5x + -1y = 0
Reorder the terms:
3x + -5x + 8y + -1y = 0
Combine like terms: 3x + -5x = -2x
-2x + 8y + -1y = 0
Combine like terms: 8y + -1y = 7y
-2x + 7y = 0
Solving
-2x + 7y = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-7y' to each side of the equation.
-2x + 7y + -7y = 0 + -7y
Combine like terms: 7y + -7y = 0
-2x + 0 = 0 + -7y
-2x = 0 + -7y
Remove the zero:
-2x = -7y
Divide each side by '-2'.
x = 3.5y
Simplifying
x = 3.5y
