Wat is the solution showing work to y= 6x y= 5x+7

1 answer:

3 0

From what I recall, just set both the equations equal to each other

6x=5x+7

6x=5x+7
-5x -5x

1x=7

x=7

Then just plug in what you found.

y=6(7)
y=42

y=5(7)+7
y=35+7
y=42

42=42

Thus, you know your answer is correct.

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:

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

C=1 because you are flipping it over the line so it cant be negative
