Answer:
4
Step-by-step explanation:
7(2m+3)-5m=2(4m+8)+9
14m+21-5m=8m+16+9
14m-5m-8m+21=16+9
9m-8m+21=25
m+21=25
m=25-21
m=4
Answer:
Let c represent the number of cows
Let h represent the number of horses
There are 2 more horses than cows in a field
⇒there are extra two horses are always than cows
⇒ horses-cows =2
⇒ hourses=2+cows
⇒ h =2+c
There are 16 animals in the field in all.
⇒ h +c=16
⇒ (2+c)+c=16
⇒ 2+2c=16
⇒ 2+2c-2=16-2
⇒2c=16-2
⇒ 2c=14
c=7
