For this case we must solve a system of two equations with two unknowns, given by "x" and "y".
We have:

We multiply (2) by -1:

We add (1) and (3):

Clearing x:

We substitute
in (2)

Thus, the solution of the system is
Answer:
the solution of the system is

Answer:
1)
2)
Step-by-step explanation:
1) The given equation is
We need to solve this for a.
In the given triangle place single variable i.e., F, on the top and variables in the product in the bottom (order of m and a does not matter) as shown in the below figure.
Using the triangle and the operations (× and ÷), we get
Therefore, the required answer is
.
2) The given equation is
We need to solve this for m.
In the given triangle place single variable i.e., p, on the top and variables in the product in the bottom (order of m and v does not matter) as shown in the below figure.
Using the triangle and the operations (× and ÷), we get
Therefore, the required answer is
.
Answer:
<h2>A. 1</h2>
Step-by-step explanation:
Use:
|a| = a for a ≥ 0 or |a| = -a for a < 0

========================================
|8 - 7| · 4 + 3(-1)
= |1| · 4 - 3
= 1 · 4 - 3
= 4 - 3
= 1
The answer is 4605 feet since 921 • 5 is 4605. There are 5 sides and each side 921 so 921 • 5 = 4605 would be the answer
