Question

Ifx=m+3andy=m-3 show that x+y+1=2
​

Answer 1

Answer:

Given equation:

2x+3y=k

Now putting x=2 and y =1 in equation

⇒2(2)+3(1)=k

⇒4+3=k

⇒k=7

Answer 2

Step-by-step explanation:

x=m+3

y=m-3

x+y+1=2

(m+3)+(m-3) +1=2

m+3+m-3+1=2

2m=2-1

m=1/2

therefore,x=1/2+3

y=1/2-3

x+y+1=2

1/2+3+1/2-3+1=2

2/2=2

=2

hence proved,

x+y+1=2
