Question

If (p,2p+1) is the solution of the linear equation 4x+3y=23. find the value of p.​

Answer 1

4x + 3y = 23

put x=p & y=2p+1

4(p)+3(2p+1)=23

10p+3=23

10p=20

p = 2

Answer 2

let x= p and y=2p+1

substituting value of x and y in 4x+3y=23

4(p)+3(2p+1)=23

4p+6p+3=23

10p+3=23

10p=20

p=2
