Thank you for the opportunity to help you with your question!

let ax+by=c         ___________(1)

lx+my=n        _____________-(2)

 be two linear equations where a,b,c,l,m,n are constants

by rearranging terms in equation one we get 

ax=c-by

x=(c-by)/a

by rearranging terms in equation two we get

x=(n-my)/l

by equating both x we get a equation in y and solve it to get value of y.

substitute value of y to get x in any one equation.


Please let me know if you need any clarification. I'm always happy to answer your questions.
