Answer:
#16 answer is D
#12 answer is A
Step-by-step explanation:
The reason #16 is D is because, if the variable "Y" is 1.5 then that would make the inequality <em>7.5 > 14</em>. This is NOT true. If "Y" were 2, then it would be <em>10 > 14</em>. This is NOT true either. If "Y" were 2.8, then that would make it <em>14 > 14</em>. THIS IS NOT true either. BUT if it was 3, then that would make it <em>15 > 14</em>. Which IS true.
Now the reason #12 is A is because the sign " " means "Greater than or equal to, no less then." And the SHORTEST/ Minimum height is 42
inches.
Hope this helps!

You can always add or subtract same value to/from both sides of equation. The same is true about multiplication and division.
In your case you have to subtract x from both sides of equation in order to get rid of it on the left side:
But it's easier to remember that if you want to move some member of equation to other side, you just have to change it's sign. Let's practice a bit using your equation (I have added "plus" signs where they are usually omitted to better understend what's going on):
Move 2y to the right side:
Move 8 to the left side:
Move both x and 2y to the right side:
