solve equation by substitution \[3x-y=0\] \[5x=2y=-44\]
OpenStudy (anonymous):
Alright, so first you would move the "Y" to the other side, giving you:\[3x=y\]
OpenStudy (anonymous):
After that, plug 3x in for y: \[5x = 2(3x) = -44\]
OpenStudy (anonymous):
\[5x= 6x +44\]
OpenStudy (anonymous):
Now solve, then plug whatever you get for x into where we got Y
