Answer 1

We have, 2x+17+y+213=27...(i)

and 2x+113+y+27=33....(ii)

Substituting 2x+11=a and y+21=b in equations (i) and (ii), we get

7a+13b=27...(iii)

and 13a+7b=33....(iv)

Adding equations (iii) and (iv), we get

20a+20b=60

a+b=3...(v)

Subtracting equation (iii) from equation (iv), we get

6a−6b=6

a−b=1...(vi)

Adding equations (v) and (vi), we get

2a=4⇒a=2

Putting the value of a in equation (v), we get

2+b=3⇒b=1

Resubstituting the values of a and b, we get

2x+11=2 and y+21=1
