Answer:
x = 3 and y = -1/2
Step-by-step explanation:
5x + 2y = 14
5x = 14 - 2y
x = (14 - 2y)/5 equation(i)
2x - 4y = 8
substitute the value of x
2(14 - 2y)/5 - 4y = 8
(28 - 4y)/5 - 4y = 8
28 - 4y - 20y = 40
-24y = 40 - 28
y = 12/-24
y = -1/2
now substitute the value of y in equation (i)
x = (14 - 2y)/5
=(14 - 2*-1/2)/5
=(14 + 1)/5
=15/5
=3
