<font face="Times New Roman" size="+2">


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 2x\ +\ 5y\ =\ 3]
*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \ x\ -\ 3y\ =\ 7]


Multiply the first one by 3 and the second one by 5


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 6x\ +\ 15y\ =\ \ 9]
*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 5x\ -\ 15y\ =\ 35]


Add the two equations


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 11x\ =\ 44]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x\ =\ 4]


Substitute *[tex \LARGE x] back in to either original equation and solve for *[tex \LARGE y]

My calculator said it, I believe it, that settles it
