C+a=166
a=166-c
5.3c+9.2a=1254.2
5.3c+9.2(166-c)=1254.2
5.3c+1527.2-9.2c=1254.2
5.3c-9.2c=1254.2-1527.2
-3.9c=-273
c=-273/-3.9
c=70
Hope this helps!

$\\ \sf\longmapsto 3s-5+2s+25=170$

$\\ \sf\longmapsto 5s+20=170$

$\\ \sf\longmapsto 5s=170-20$

$\\ \sf\longmapsto 5s=150$

$\\ \sf\longmapsto s=30$
