Subtract the second equation from double the first equation:
2x+6y-2x-(-4y)=0
10y=0
Therefore, y=0. Substituting this into the first equation, we see that:
x+3(0)=3
x=3
Therefore, x=3. The solution to this system is x=3, y=0, or (3, 0).
4x+26
Step-by-step explanation:
to buy fencing, you need to find the perimeter of the pen. The perimeter is found by adding all sides together.
So, 13+13+2x+2x=4x+26
This is how I did it:
use distribution
use addition
use addition and subtraction
use division
So your answer is
In number form, your question is:
14 5/9 + 6 7/9 = ?
We can now understand this easier, and answer it.
Add your whole numbers first to not get confused.
14 + 6 = 20.
Now add your fractions.
5/9 + 7/9 = 12/9, = 1 3/9.
Add 1 to your whole number.
20 + 1 = 21.
You are left with 21 3/9.
Your answer is 21 3/9.
I hope this helps!
