Answer:
e.) -4b -24
Step-by-step explanation:
Substitute the expression for "a" into the expression -2a. Make use of the distributive property to eliminate parentheses.
... -2a = -2(2b +12) = -4b -24
Answer:
2a + 4b = 44
a+b=15
Step-by-step explanation:
Call a the number of chickens, b the number of horses
We have: 2a + 4b = 44
a + b = 15
=> 2(a+b) = 30
<=> (2a + 4b) - (2a + 2b) = 14
2b = 14
=> b = 7
=> a = 8
So 8 chickens, 7 cows.
