Simplifying 4x + -3y = 1 Solving 4x + -3y = 1 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3y' to each side of the equation. 4x + -3y + 3y = 1 + 3y Combine like terms: -3y + 3y = 0 4x + 0 = 1 + 3y 4x = 1 + 3y Divide each side by '4'. x = 0.25 + 0.75y Simplifying x = 0.25 + 0.75y
