Multiply equation (1) and (2) by 4 to remove the fractions.



Multiply equation (4) by 7

7x + 98y = 224 ---(5)


Subtract equation (3) from equation (5)

7x + 98y - (7x - 10y) = 224 - 8

7x + 98y - 7x + 10y = 216

108y = 216

y = 216/108

y = 2


Substitute value of y in equation (4)

x + 14(2) = 32

x + 28 = 32

x = 32 - 28

x = 4


So solution is (4, 2).

x = 4, y = 2
