Given the statement:

A number, triple a number and -4 are added, the result is 60.

Let's find the number.

Let x represent the unknown number.

To find the unknown number, let's write an equation to represent this situation.

We have:

• A number: ,x

• Triple a number: ,3x

• A number, triple a number and -4 are added: ,x + 3x + (-4)

• A number, Triple a number and -4 are added, the result is 60: ,x + 3x + (-4) = 60

Hence, we have the equation:

x + 3x + (-4) = 60

Let's solve for x.

x + 3x - 4 = 60

4x - 4 = 60

Add 4 to both sides:

4x - 4 + 4 = 60 + 4

4x = 64

Divide both sides by 4:


\begin{gathered} (4x)/(4)=(64)/(4) \\ \\ x=16 \end{gathered}

Therefore, the unknown number is 16.

ANSWER:

16
