Answer:
[ multiply (1) & (2) by exchanging the coefficients of y ]
2x − y = 3 ------(1). × 2
3x + 2y = 8-----------(2). × 1
4x - 2y = 6 ----------(3)
3x + 2y = 8----------(4)
By adding (3) & (4)
4x - 2y = 6
3x + 2y = 8
__________
7x +0 = 14
7x = 14
x=14/7
x = 2
Substitute the value of x in (1)
2x − y = 3
2(2) − y = 3
4-y = 3
y = 4-3
y = 1
