Bryson and lilly played a game of darts and lilly scored 4 more the Bryson the total of the score was 180 how many points did each of them score

Well, we know that Lilly scored 4 more points than Bryson. So we could write that 
Lilly's score = Bryson's score plus 4. Or L=B+4 Now we also know that 
Lilly's score + Bryson's score = 180. So L+B=180 Now We can substitute in L in the second equation to get B+B+4=180 so B+B=176 and B=88 The we put B into the first equation and find that 
L=92.
