I find from the first equation that x = 3y and plugging in to the second equation we get
o.2y+37(3y)=23
0.2y111y=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?

bobpursley,
without both equations, I do not have a clue either.

unknown,
12y +4x=0
0.2y+37x=23
does this help
