Hope it helps.

Answer 2

Answer:

Hence the value of y is 2.

Step-by-step explanation:

As per the data given in the above question,

The given equation is $x+y=7$

Where x is equal to 5,

We have to find the value of y,

Here we have to use the substitution method,

The equation is,

$x+y=7$

Substitute the value of x=5 in the above equation we get,

$5+y=7$

Minus both sides in the above equation, we get,

$5-5+y=7-5\\y=2$

Hence the value of y is 2.
