What are the solution of these 1.) 4x+2y=-8 2.) 3x+y=3, 3.) 5x-3y=9 using the Cramer's rule ?
x+y= -1 x-y=7 x+2y=9

Hello,

Which system of two equations do you want to solve?
I see here three equations in two unknowns.

The Cramer's rule is applicable to systems with squared matrices.
So, you should present two equations in two unknowns
or three equations in three unknowns.

Do you understand my trouble?

My advice to you: do not try to load too many problems into one request.
It is against you.
It is against us, tutors, too.
