Question

Four times a number is added to 12 the result is -28

Answer 1

-10

Step-by-step explanation:

Let's call the unknown number x.

Four times this number is 4*x

Then, four times a number is added to 12 the result is -28 can be written as:

4*x + 12 = -28

So, we can solve the equation for x by subtracting 12 from both sides:

4x + 12 - 12 = - 28 - 12

4x = -40

Then, dividing by 4 into both sides, we get:

`\begin{gathered} (4x)/(4)=-(40)/(4) \\ x=-10 \end{gathered}`

So, the unknown number is equal to -10
