Question 3518: A taxi charges an initial charge of $3. Your fare will be computed as the $3 charge plus 20 cents for every mile traveled.

4.70 = 3+.20x
Subtract 3 from each side to isolate the variable.
4.70-3 = 3+.20x-3
1.70 = .20x
Divide .20 from each side:
1.70/.20 = .20x/.20
8.5 = x
Check:
4.70 = 3+(.20)(8.5)
4.70 = 3+1.7
4.70 = 4.70
