Respuesta :
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.

Answer : The score of Bryson and lilly is, 88 and 92 respectively.
Step-by-step explanation :
Let the score of Bryson be, 'x'
So, the score of lilly will be, [tex]x+4[/tex]
Given:
Total score = 180
So, the equation will be:
[tex]x+(x+4)=180[/tex]
[tex]2x+4=180[/tex]
[tex]2x=180-4[/tex]
[tex]2x=176[/tex]
[tex]x=\frac{176}{2}[/tex]
[tex]x=88[/tex]
The score of Bryson = x = 88
The score of lilly = x+4 = 88+4 = 92
Thus, the score of Bryson and lilly is, 88 and 92 respectively.
