Answer 1

I hope this will help you

Step-by-step explanation:

x = m+3

y = m-4

to prove x+y+1= 2m

putting the value of x and y in x+y+1

We get,

m+3+m-4+1= 2m

2m+4-4= 2m

2m = 2m

Hence, proved

Answer 2

Answer:

x = m + 3 => x - 3 = m ---------(1)

y = m - 4 => y + 4 = m ---------(2)

Add (1) & (2),

x - 3 + y + 4 = m + m

x + y + 1 = 2m.

Hence Proved
