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

• on solving the equation,
  3x+4y=10-------->1
  3x+3y=6--------->2
  we get the value as y=4 and x=-2
  substitute this value in 3x+11y and the ans will be 38.
  
  therefor the ans is 38

• 38
  subtracting two equations we got y=4;
  so
  3x+11y
  =3x+4y+7y
  =10+7y
  =10+7*4
  =38;

  We have,
  3x+4y=10............(1)
  3x+3y=6.............(2)
  we get the value as x=-2 & y=4
  substituting these values in 3x+11y, the ans will be 38.
