Answer 2

Answer:

x = 41/13, y = 34/13

Step-by-step explanation:

5x+2y=21----(i) and 4x-y=10----(ii)

multiplying (ii) with 2-->

8x-2y =20

now by eliminating y through addition, we get-->

13x = 41

x=41/13

putting the value of x in (ii)----->

4×41/13 - y = 10

164/13 -10 = y

164-130/13 = y

34/13= y

Thank you!
