Hilda adds 5 to a number, then multiplies the sum by negative 2. The result is 6. Write an equation to find the number, x.
What is the number? Enter your answer in the box.

Respuesta :

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 .
