The scenario will will be represented by: [tex]x+x+2x+4x=-104[/tex]
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"
[tex]x+x+2x+4x=-104[/tex]
This can also be written as:
[tex]x+x+2x+4x=-104\\8x=-104\\Dividing\ both\ sides\ by\ 8\\\frac{8x}{8}=\frac{-104}{8}\\x=-13[/tex]
