Question

If (m, 4-m) lies on the graph of the equation x + y = 2+n,
then the value of n is
a) 1
b) 2.
c) -3
d)
-2.​

Answer 1

Answer:

2

Step-by-step explanation:

It is given (m , m-4) which shows that the value of

x=m

y=m-4

So put these values in the equation and solve for value n

x + y = 2 + n

= m + 4 - m = 2 + n

= 4 = 2 + n

= n =2

So the value of n is 2
