OpenStudy (sepeario):
y = 2x + 5 y = 0 - 5 + 2x 2x + 5 = 0 - 5 + 2x Can you work it from there? I'm still kind of learning this, I'm not really sure. You might need someone better with this to help...
jimthompson5910 (jim_thompson5910):
-2x + y + 5 = 0 -2x + 2x + 5 + 5 = 0 ... replace y with 2x+5 (since y = 2x+5) 0x + 10 = 0 0 + 10 = 0 10 = 0 this last equation is false, so there are no solutions
