3x + y =5 dan 3x - 2y=11

you simply put 40 over a hundred and 55 over n (which is the number were trying to find) so you do cross multiplication. 55 times a hundred and after you get the answer. You divide it by 40 and should get 137.5.

55 is 40% of the number 137.5. To find this, we set up the equation 0.40 times x equals 55 and solve for x. Dividing 55 by 0.40 gives us the final result of 137.5.
