OpenStudy (kira_yamato):
I need another equation... The relationship between x and y is x = 2 - 16y/3
OpenStudy (anonymous):
\[15x+40y=32\]
OpenStudy (anonymous):
Use the value for X that Kira got and plug it into the second equation, then solve. 15(2 - 16y/3) + 40y = 32 30 - 80y + 40y = 32 -40y = 2 y = -1/20 Then plug the value for Y into the first equation. x = 2 - 16(-1/20)/3 x = 4 2/5
OpenStudy (anonymous):
That's 4 and 2/5 or 4.4
