If the mystery number is x then:
Hilda adds 5 to a number: x + 5
multiplies the sum by negative 2: (x + 5)*- 2 which is -2(x + 5).
(Use parentheses for "x+5" because Hilda added 5 to x first before multiplying it by -2)
So the equation to find the number x is -2(x + 5)

Answer: Required equation : [tex](x+5)\times-2=6[/tex]
The number is -8 .
Step-by-step explanation:
Let x be the number .
Given : Hilda adds 5 to a number, then multiplies the sum by negative 2. The result is 6.
According to the statement , we have
[tex](x+5)\times-2=6[/tex]
Required equation : [tex](x+5)\times-2=6[/tex]
To solve for x , first we divide both sides by -2 , we get
[tex](x+5)=-3[/tex]
Subtracting 5 on both sides , we get
[tex]x=-8[/tex]
Hence, the number is -8 .
