Answer: Y = 46

Step-by-step explanation:

We're given the scenario:
2y-5x=12 and we let x = 16.

  1. Since x = 16 we can do -5(16) which equals -80. Making the problem look like this.
    2y-80=12
  2. Now we can add -80 on both sides in order to keep 2y by itself. After completing this process we are left with this equation.
    2y=92
  3. Lastly we would divide 92/2 to get y by itself. We are left with
    y=46

Check:

We can check our answer by plugging in what x and y is being 16 and 46 respectively.
2(46)-5(16)=12 and since 12=12, our answer is true.
