Answer 1

Answer: 126days

Step-by-step explanation:

6m+5w=6        

4m+3w=10

(multiply with 4 )24m+20w=24 -----a(assume)

(multiply with 6) 24m+18w=60------b(assume)

=(a-b)

2w=-36

w=36/2

w=18

24m+20*18=24

24m-360=24

24m=384

m=384/24

m=16

9m+15w=?

9*16+15*18=z(assume)

144-270=126days
