Answer:

4y = 3

Step-by-step explanation:

To subtract the 2nd equation from the first, negate all three of the second equation terms:  3x + 2y = -4

and then add (combine) this result to (with) the first equation:

 -3x + 2y = 7

  3x  +2y = -4

----------------------

           4y = 3  (this is the desired result))
