Applications of Linear Systems

Using data for years 1985 to 1990, the function y=8x+31.6 can be used to estimate the first trend, while the function y=5.1x+35 can be used to estimate the second trend. For both functions, x is the number of years since 1985. If these trends continue, in what year are the two trends equal?
