Question 1172055: Michelle solved this system of equations
using the elimination method:
5y=3x-2
-3y=x+18
Here is her work:
5y=3x-2
-3y=-3(x+18)--->-3=-3x-54
Then she added the equations:
5y=3x-2
+-3y=-3x-54
_
2y=-56
y=-28
=3(-28)=x+18
84=x+18
x=66
Did Michelle solve the problem correctly?
If not, explain where she made a mistake
and solve for the correct answer.
