A number plus itself, plus twice itself, plus 4 times itself is equal to -104

NARA [144]

The scenario will will be represented by: $x+x+2x+4x=-104$

The number will be -13

Step-by-step explanation:

We have to convert the given situation into the mathematical form

Let x be the number

Then

"a number plus itself"

x+x

"plus twice itself"

x+x+2x

"plus 4 times itself"

x+x+2x+4x

"is equal to -104"

$x+x+2x+4x=-104$

This can also be written as:

$x+x+2x+4x=-104\\8x=-104\\Dividing\ both\ sides\ by\ 8\\\frac{8x}{8}=\frac{-104}{8}\\x=-13$

What is the result of subtracting the second equation from the first?<br> -2x+y=0<br> - 7x + 3y = 2

artcher [175]

Answer:

5x - 2y = - 2

Step-by-step explanation:

Given the 2 equations

- 2x + y = 0 → (1)

- 7x + 3y = 2 → (2)

Subtracting (2) from (1) term by term

- 2x - (- 7x) + y - 3y = 0 - 2, that is

- 2x + 7x - 2y = - 2

5x - 2y = - 2
