For which value of \lambda, do the simultaneous equations 3x+4y=\lambda and 6x+8y=2 have infinite solutions.
\lambda = 0
\lambda = 1
\lambda = 2
\lambda = 3
Divide both sides of the equation 6x+8y=2 by 2 to simplify the equation
3x+4y=1
substrate the above equation from the equation 3x+4y=\lambda. We get
\lambda =1
