Question 165424: "If 2/3 of a number is added to the number, the result is 110. Find the numbers"
My solution:
2/3 = 67%
110 x 67% = 73.7
110 - 73.7 = 36.3
or
110 / 3 = 36.67
Therefore 2/3 would be 73.34 + 36. 67 = 110
Would both be correct, or neither?

Judy averaged 42 miles per hour(mph) driving from Allentown to Harrisburg and 51 mph driving from Harrisburg to Pittsburg. If she drove a total of 288 miles in 6 hours, then how long did it take her to drive from Harrisburg to Pittsburg?
I set this up a 2 equations using a chart as: Distance Speed Time
Allentown to Harrisburg x 42 42x
Harrisburg to Pittsburg y 51 51y
Allentown to Pittsburg 288 288/6=48 6
Now x + y = 288
42x + 51y = 6 by substitition using y = 288 - x
42x + 51(288-x) = 6
42x + 14,688 -51x = 6
-9x = -14,682 and x = 1631.33
It works out when you plug back in, but can't be true since there is a total of only 288 miles. The y then is a negative number which satisfies the equation. Pleas help. Thanks Claudia
