<PRE><B>Question 1163878</B>
s = number of years sleeping
w = number of years watching tv
s + w = 33
s = w + 17
substitute w + 17 for s to get s + w = 33 becomes w + 17 + w = 33
combine like terms and subtract 17 from both sides of this equation to get 2w = 16
solve for w to get w = 8
s - w = 33 - 8 = 25
the person will spend 25 years sleeping and 8 years watching tv.
25 + 8 = 33 = total time sleeping and watching tv.
25 - 8 = 17 = number of years sleeping exceeds number of years watching tv.
your solution is 25 years sleeping and 8 years watching tv.
