3/7x+5=8. I tried to cross-mulitplied and I got 3x+35=8. I divided -27 by 3 and I got -9. Is this right? Not quite. Given 3/7x + 5 = 8 Multiply through by 7x yields 3 + 35x = 56x 3 = 21x making x = 1/7.

I do not get 100 miles. Here is a better way to set up the equation: let d = the distance between the two houses. The total time is 4 hours. The time spent traveling can be found by manipulating V = d/t t = d/V So the time is the displacement divided by the velocity. 45/d + 55...
