Homework Help: math116

Posted by unknown on Tuesday, October 19, 2010 at 10:01pm.

I find from the first equation that x = 3y and plugging in to the second equation we get
o.2y+37(-3y)=23
0.2y-111y=23
-110.8y=23
y=-23/110.8
x=69/110.8
need help to understand why the elimination process in not work in this linear equation?
