Simplifying 8x + -6y = -20

Solving 8x + -6y = -20

Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right

Add '6y' to each side of the equation. 8x + -6y + 6y = -20 + 6y

Combine like terms: -6y + 6y = 0 8x + 0 = -20 + 6y 8x = -20 + 6y

Divide each side by '8'. x = -2.5 + 0.75y


Simplifying x = -2.5 + 0.75y
