ANSWER :-
2x + y = 6 ----------------------(1)
4x - 2y = 3 -----------------------(2)
From equation (1) we find y = 6 - 2x
put this value of y in (2)
we get , 4x - 2y = 3
4x - 2(6-2x) = 3
4x - 12 + 12x = 3
16x - 12 = 3
16x = 3 + 12
16x = 15
x = 15/16
Put the value of x = 15/16 in (2)
4(15/16) - 2y = 3
60/16 - 2y = 3
60 - 32y / 16 = 3
60 - 32y = 16 × 3
60-32y = 48
60-48 = 32y
12 = 32y
12/32 = y
6/16 = y
3/8 = y
