How to solve the equation of 3 / x + 4 / y = 2 3x-4y = 7

How to solve the equation of 3 / x + 4 / y = 2 3x-4y = 7


Equation (1) multiply both sides by 36, get: 12x + 9y = 72 (3) equation (2) multiply both sides by 4, get: 12x-16y = 28 (4) substitute (3) - (4), get: 25y = 44, y = 44 / 25 into (2), get: 3x-176 / 25 = 7
