If 3y+x>2 and x+2y ≤3, what can be said about the value of y ?
a. y = -1 b. y > -1 c. y < -1 d. y =1

• ans is b
  3y+x>2 =>2y+x+y>2
  3+y>2
  hence y>-1

• 3y+x>2---->(1)
  x+2y(2)
  eqn(2)*-1--->-x-2y 2
  -x-2y-1

  ans:(b)

• Can anyone correct the second equation?????

• 3y+x>2 is only possible when y value is always positive so y>-1
• 11 years agoHelpfull: Yes(1) No(0)
• answer is b that is y>-1

• simply convert all unequality signs in to equality and tan solve 2 equations 3y+x=2
  2y+x-1).

• ans: y=1
  convert > symbol as equal sign(=). thn solve it.

• 3y+x>2 can be written as x>2-3y ....1st equation
  x+2y
