Slower bike = X

Faster bike = X+9

They both ride for 2 hours, now you have 2x and 2(x+9)

The sum of the two cyclists is 66 miles:

2x +2(x+9) = 66

Use distributive property:

2x + 2x+18 = 66

Simplify:

4x +18 = 66

Subtract 18 from both sides:

4x = 48

Divide both sides by 4:

x = 48/4

x = 12

The slower bike was going 12 mi/h

The faster bike was 12+9 = 21 mi/h.
