Substitute your x = 2y2 for x in the second equation. and solve for y.

Once you have your y, plug in that value back for the first equation to get your x.

3(2y  2)  y = 14
5y6 = 14
y=4 => x=6

5y6=14 i get that but what did you do after that?

5y = 14+6
5y = 20
y=4
them from 3x  y = 14
3x  (4) = 14
3x = 18
x=6
so (6,4)
