Answer:

5x - 6 = 44
(add 6 to 44)
5x=50
(divide 5 into 50)
x=10
In the first problem, the student is trying to find the solution of the two equations
so the student should use both equations
what the student did was only use the 2nd equation twice (if you use the same equation there are infinite solutions) when he/she should have used both equations
for the 2nd problem
trashaway=0.25x+25 where x=number of pounds
garbagenomore=45
solve where they intersect or where they are equal
45=0.25x+25
20=0.25x
80=x
80lb
