# Find the solution of the system of equations2x + 3y = 9; 3x + 4y = 5

2x + 3y = 9 ……equation (i)

3x + 4y = 5 ……equation (ii)

Multiplying equation (i) by 3 and multiplying equation (ii) by 2 we get

6x + 9y = 27 ….equation (iii)

6x + 8y = 15 …..equation(iv)

Subtracting the above two equations we get

y = 12

2x + 36 = 108

2x = 72

x = 36

Answer: x = 36, y = 12
