The numerical coefficient of this term is -3.
Answer:
<em>x = 1</em>
<em>y = 1</em>
Step-by-step explanation:
<u>System of Equations</u>
We are given the system of equations:
2x + y = 3
x = 2y - 1
Substituting x in the first equation:
2(2y - 1) + y = 3
Operating:
4y - 2 + y = 3
5y = 3 + 2
y = 5/5 = 1
y = 1
Since:
x = 2y - 1
Then:
x = 2(1) - 1
x = 1
Solution:
x = 1
y = 1
Answer:
This is a trial and error problem
we can divide 30 eyes by 2 eyes on each animals to know that there is 15 animals
15 animals now make a random guess
Find out the difference of feet. 1 dog has 4 feet - 2 chicken feet = 2 feet increase or decrease so if we need to increase by 2 we add 1 dog and if we need to subtract to then we add 1 chicken
11 dogs and 4 chickens
that is 44 feet + 8 feet = 52 feet
52 - 44 feet needed = 8 feet
8 / 2 feet decrease = 4 more chickens needed
11 - 4 (subtracting 4 dogs off)= 7
4 + 4 (replacing the dogs with chickens)= 8
7 dogs and 8 chickens
7 x 4 = 28
8 x 2 = 16
28 + 16 = 44
7 dogs and 8 chickens
