for 43w>8

algebra 1 
Reiny,
Here would be the correct solution ...
43w > 8 OR 4 + 3w > 8
3w > 4 OR 3w > 12
w < 4/3 OR w > 4
You didn't state what Paul had said. 
algebra 1 
mark,
thats what he had for an answer but he thinks a reasonable answer is w= 3 why though? and why is it incorrect?

algebra 1 
Reiny,
w = 3 is a "reasonable" answer because it satisfies the original inequation, and it falls within the domain of my solution.
There are an infinite number of reasonable answers.
check:
if w = 3
LS = 4  3(3)
= 4+9
= 13
Is 13 > 8 ??? YES, so w = 3 is one of the infinite number of solutions.
