\(\frac{S}{P} = \frac{4}{11}\)
\(11s = 4p\)
from question s + 84 = P
Multiplying by four on both sides we get,
4s + 336 = 4p
replace 11s for 4p to get,
4s + 336 = 11s
or, 336 = 7s
Therefore, s = 48
\(11s = 4p\)
from question s + 84 = P
Multiplying by four on both sides we get,
4s + 336 = 4p
replace 11s for 4p to get,
4s + 336 = 11s
or, 336 = 7s
Therefore, s = 48
