You would start with the equation:Let m=number of miles
49.98+0.12m=35.98+0.17m
Then solve for m
You would then get
49.98+0.12m=35.98+0.17m
-0.12m -0.12m
49.98=35.98+0.05m
-35.98 -35.98
14 = 0.05m
---- --------
0.05 0.05
280=m
First you set f(x) and h(x) equal to each other. So 1/x+1=2x+3. Next, you multiply each side by 1 to cancel out the fraction. So now the answer is x+1=2x+3. Now subtract 1 from each side. X=2x+2. Subtract 2x from each side now. -2x=2. Divide by -2x and get the answer x= -1
