⠀⠀⠀⠀

3x + 2y = 7 ---- ( i )

⠀⠀⠀⠀

4x - y = 2 ---- ( ii )

⠀⠀⠀⠀

Multiply eq ( ii ) by 2

⠀⠀⠀⠀

8x - 2y = 4 ---- ( iii )

⠀⠀⠀⠀

Adding eq i and ii

⠀⠀⠀⠀

3x + 2y + 8x - 2y = 7 + 4

⠀⠀⠀⠀

3x + 8x = 7 + 4

⠀⠀⠀⠀

11x = 7 + 4

⠀⠀⠀⠀

11x = 11

⠀⠀⠀⠀

x = 11 / 11

⠀⠀⠀⠀

x = 1

⠀⠀⠀⠀

putting value of x in eq ( i )

⠀⠀⠀⠀

3x + 2y = 7

⠀⠀

3 × 1 + 2y = 7

⠀⠀⠀⠀

3 + 2y = 7

⠀⠀⠀⠀

2y = 7 - 3

⠀⠀⠀⠀

2y = 4

⠀⠀⠀⠀

y = 4 / 2

⠀⠀⠀⠀

y = 2
