3x+4y=10
x3 + y3=6
What is the minimum value of 3x+11y=?

• By solving the two gvn eqns,we get x=-2 and y=4. so by substituting these values in 3rd eqn we get 3(-2)+11(4)=38. so ans is 38.

• if x is equal to -2, x cube is -8, but if y = 4 , y cube is 64.... second equation is not satisfying (-8) + (64) = 56. its not equAL TO 6
