Answer 1

Hai friend,

here is your answer,


2x+5y=18
2*2+5y=18
4+5y=18
5y=18-4

5y=14

value of 5y=14

4x+5y=4*2+5y=8+14=22

Value of 4x+5y=22

hope helped!!

Answer 2

Hey friend!

2x + 5y = 18
2 (2) + 5y = 18
4 + 5y = 18
5y = 18 - 4
5y = 14

therefore the value of 5y = 14

4x + 5y
4 (2) + 5y
8+14
=22

4x + 5y = 22

Option C is correct.

Hope it helps..!!
