twenty-eight less than andrew's age is one hundred sixty less that five times his age. how old is andrew?
( show work! )

X is Andrews age and if x stands for Andrew then

x-28=5x-160

then you would do =+160 to both sides getting x+132=5x

subtract the x from the side with 132 and then do 4 divided by 132
getting 33
Andrew is 33

Bis your answer. it only holds the decimal numerals
