Well, we know that Lilly scored 4 more points than Bryson. So we could write that <span>Lilly's score = Bryson's score plus 4. Or L=B+4 Now we also know that </span> <span>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 </span> <span>L=92.</span>
