Answer:
Multiply the second equation by −2 to get −8x − 6y = −30.
Step-by-step explanation:
{2x + 6y = 12
{4x + 3y = 15
{2x + 6y = 12
{−8x − 6y = −30 >> New Equation
* Doing this will give you <em>additive</em><em> </em><em>inverses</em><em> </em>of −6y and 6y, which result in 0, so they are both ELIMINATED.
** [3, 1] is your solution.

Answer:
See below.
Step-by-step explanation:
So, we have:

PART A:
Find the GCF. Notice that we have a 3 in every term and a p in every term. Thus, the GCF is 3p:

This is the most we can do.
PART B:
Continue from where we left off. Factor the entire expression:

Hi there!
So you're looking at an equilateral triangle, which is a big word that basically means all three sides are equal and all three angles are 60°.
Knowing that, the mesure of one side is 7, so necessarily the side "x" is also equal to 7.
So the value of x is : 7
And since all angles are of 60°, necessarily the angle "y" has an angle of 60°.
So the value of y° is : 60°
There you go! I really hope this helped, if there's anything just let me know! :)
Resolviendo una resta, veremos que el número es igual a 12.
<h3>
¿Como encontrar el número?</h3>
Definamos X como nuestro número, sabemos que cuando este número es disminuido en cuatro (es decir, le restamos 4 a nuestro número X) el resultado es 8.
Entonces, lo que tenemos que hacer es resolver la operación:
X - 4 = 8
Para resolver esto, lo que tenemos que hacer es sumar 4 en ambos lados de esta ecuación, asi obtenemos:
X - 4 + 4 = 8 + 4
X = 12
De esta forma, concluimos que nuestro número es igual a 12.
