It might not end up being any help... but divide the first equation by 3 to make the numbers smaller:
[3]
Multiply [3] by -8 and add the resulting equation to [2]; that will eliminate x.
[4]
[2]
[4]+[2]
Plug y=10 in either of the original equations to solve for x.
I leave that part to you to finish the problem....

Your original system of equations in the post is written in some STRANGE and UNUSUAL MANNER.
Twice and thrice check it; then re-check and cross-check.
Happy checking, double-checking, re-checking and cross-checking (!)

Notice that the tutor @greenestamps instructed you on solving ANOTHER/DIFFERENT system (!)
