Question

P=M÷6.C=M÷2.P+C+M=100.Afla P,M,C.

Answer 1

P=M÷6. 
C=M÷2. 
P+C+M=100
[tex] \frac{M}{6} + \frac{M}{2} +M=100 [/tex] (aducem la acelasi numitor comun)
$\frac{M}{6} + \frac{3M}{6} +M=100$
$\frac{4M}{6} +M=100$ (inmultim toata ecuatia cu 6)
4M+6M=600
10M=600
M=60
P=M:6 = 60:6 = 10
C=M:2 = 60:2 = 30
