If its a reflection across the y axis the x value is reflected and the y value stays the same, so (-3,7)
I belive the answer would be....
49.5-37.5=12
2•12=24
and 
use the second expression to calculate the left-hand side of the first equation:

Add 10 to both sides if this equation to get

and divide both sides by 2

this proves that x = 17, give the two initial equations
