help with solving in math

Question

Salma will rent a car for the weekend. She can choose one of two plans. The first plan has an initial fee of $47.98 and costs an additional $0.16 per mile driven. The second plan has an initial fee of $51.98 and costs an additional $0.12 per mile driven. How many miles would Salma need to drive for the two plans to cost the same?

Answer 1

lets say x represent # of miles driven. so;

47.98 +0.16x = 51.98 +0.12x (first get rid of decimals by multiplying each by 100)

4798 +16x = 5198 +12x

please solve for x, if you need more assistance please let me know
