Quick way:

system%28xy=60%2C+2x%2B2y=34%29

x%2By=17
y=17-x
-
x%2817-x%29=60
-x%5E2%2B17x-60=0
x%5E2-17x%2B60=0

D=17%5E2-4%2A60
D=49

x=%2817%2B-+7%29%2F2
The subtraction form will work.
x=5 and from xy=60,
y=60%2F5
y=12

One of the possibilities is dimensions 5 and 12.

The PLUS form for x should also work.
x=17%2B7%2F2
x=24%2F2
x=12, which would just give y=5.

DIMENSIONS, 5 AND 12.
