ok
OpenStudy (anonymous):
U have to multiply the 2nd expression by 5 then sum both of them, u will se that y goes away and u have a simple equation where u can find x
OpenStudy (griffindore):
ok thanks
OpenStudy (griffindore):
so i get rid of y then it should give me x then i can substitute x with whatever it is then i'll get y?
OpenStudy (anonymous):
