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 (!)
