Question

3 X + 2 Y = 7 and 3 X + Y = 1

Answer 1

3X + 2Y = 7 ----(1)

3X + Y = 1 ------(2)

/* Subtract eqution (2) from eqution (1) , we get */

Y = 6

/* Put Y = 6 in equation (2) we get */

3X + 6 = 1

$\implies 3X = 1 - 6$

$\implies 3X = -5$

$\implies X = \frac{-5}{3}$

Therefore.,

$X = \frac{-5}{3}$

$Y = 6$
