Please explain to me how to solve this problem:

Reid and Maria both play soccer. This season, Reid scored 4 less than twice the number of goals that Maria scored. The difference in the number of goals they scored was 6. How many goals did each of them score?

2 answers

maria ---> x goals
Rein ----> 2x-4

2x-4 - x = 6
x = 10
Maria scored 10 and Reid scored 16 goals.
