CAN ANYONE PLEASE HELP ME I HAVE NO CLUE WAT TO DO AND I AM SO CONFUSED HELP ANYONE PLEASE
4x5y=19
2x+17=y
what is the solution of the system?

Reiny
I would use substitution here.
your second equation describes what y is
It said y = 2x+17
so sub that into the first
4x + 5y = 19
4x + 5(2x+17) = 19
4x + 10x + 85 = 19
14x = 104
x = 104/14
x = 52/7
