Neporo4naja [7]

Answer:

The system of equations is

$x+y=15$

$19x+8y=164$

Step-by-step explanation:

Let

x------> the number of videos of new releases

y-----> the number of classics videos

we know that

$x+y=15$ ------> equation A

$19x+8y=164$ ------> equation B

Using a graphing tool

Solve the system of equations

Remember that the solution of the system of equations is the intersection point both graphs

The intersection point is $(4,11)$

see the attached figure

therefore

the number of videos of new releases is $4$

the number of classics videos is $11$

What is the value of x that makes the given equation true? 2(x−8)=x+5x

bixtya [17]

Simplify the right hand side:

$2(x-8)=6x$

Expand the left hand side:

$2x-16=6x$

Subtract 2x from both sides:

$-16=4x$

Divide both sides by 4:

$x=-4$
