Answer:
x = -0.8y
Step-by-step explanation:
Simplifying
4y + 5x = 0
Reorder the terms:
5x + 4y = 0
Solving
5x + 4y = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4y' to each side of the equation.
5x + 4y + -4y = 0 + -4y
Combine like terms: 4y + -4y = 0
5x + 0 = 0 + -4y
5x = 0 + -4y
Remove the zero:
5x = -4y
Divide each side by '5'.
x = -0.8y
Simplifying
x = -0.8y
