Liam's runs --- x
Brogran's runs --- x-10
Shanno's runs --- x - 15
Amy ---- x-10 - 6 = x - 16
emily --- x-16 - 8 = x - 24
x+x-10+x-15 + x-16 + x-24 = 220
5x = 285
x = 57
so Lima has 57 runs
Brogan has 47 runs
Shannon has 42 runs
Amy has 41 runs
emily has 33 runs
All works out
Liams cricket team scored 220 runs,
Liam scored 10 more runs than Brogan and 15 more than shannon
amy scored six runs less than brogan and eight more than emily
how many runs did shannon score
please i cried on this question i need help and im not going to just guess every number in the counting range and perform some medical operation on it there has to be another way to do this

thanks mathhelper
L = B + 10
L = S + 15
A = B - 6
A = E+ 8
L + S + B + A + E= 220
S + 15 + S + B +A + E = 220
B = L - 10
B = S + 15 - 10 = S + 5
S + 15 + S + S+5 + A + E = 220
3 S + 20 + A + E = 220
3 S + (B-6) + E = 200
3 S + (S+5-6) + (A-8) = 200
4 S - 1 + (B-6-8) = 200
4 S - 15 + B = 200
4 S - 15 + (S+5) = 200
5 S - 10 = 200
5 S = 210
S = 42
