6x-28 is what I got for this
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

Step-by-step explanation:
Let x be the amount invested at 7% and y the amount invested at 6%
We know that the yearly interest earned = 0.07(x) and 0.06(y)
x+y =4500
0.07x +0.06 y =290
Solving the equations will give , x = $2,000 and y=$2,500
24 would be a common denominator
