Answer by Abhira Singh

X=4 and Y=3

Step-by-step explanation:

3x + 2y = 18 ---- eq (1)

7x - 2y = 22 ---- eq (2)

By simultaneous method , adding eq (1) and (2)

3x+ 2y = 18

+ 7x - 2y = 22

-------------------------

10x = 40

x= 4

put x=4 in eq 1

3x + 2y = 18

3(4) + 2y = 18

12 + 2y = 18

2y = 18 - 12

2y = 6

y = 3
