Hello friend,here is the solution
<span>Let x be the total distance </span>
<span>Distance travelled by rail = 3/5 x </span>
Distance travelled by taxi = 1/4 x
<span>Distance travelled by bus = 1/8 x </span>
<span>The equation we obtain is </span>
========================
<span>x = 3/5 x + 1/4 x + 1/8 x +2 </span>

<span>hope this solution helps you......</span>
Ur output value is f(x).....so to do this problem u need to sub in 2/3 for f(x) and solve for the input value which is x
f(x) = -1/3x + 7
2/3 = -1/3x + 7 ...multiply everything by 3
2 = -x + 21
2 - 21 = - x
- 19 = -x
19 = x <== ur output
