Question

5x=y and 2x+y= 7 so find the value of y​

Answer 1

Answer:

5x=y ------1equation

2x+y= 7

2x +5x =7 (Using 1)

7x=7

x=7/7

x=1

Putting the value of x in 1

5x=y

5 (1)=y

y=5

Therefore, x=1 and y=5.

Answer 2

Step-by-step explanation:

5x = y

and , 2x + y = 7

so, 2x + 5x = 7

7x = 7

x = 1

Now, y = 5x

= 5(1) = 5
