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
