Answer :


4(x + 2) + 7(y - x) = 28(2x - 8) (Multiplying both sides by 28)


59x - 7y - 232 = 0



(2y - 3x) + 6y = 3(3x + 4) (Multiplying both sides by 3)


12x - 8y + 12 = 0


3x - 2y + 3 = 0



To solve the equation by cross multiplication method, we use:



Putting the values, we get:




So, and


x = 5 and y = 9
