Question

The sum of 5 times a number and 4 equals 2. Find the number

Answer 1

Answer:

-2/5

Explanation:

Let the number = x

5 times a number = 5x

'Sum' means addition, therefore:

The sum of 5 times a number and 4 =5x+4

We then have the equation:

$5x+4=2$

We now solve for x.

$\begin{gathered} 5x+4-4=2-4 \\ 5x=-2 \\ \frac{5x}{5}=-\frac{2}{5} \\ x=-\frac{2}{5} \end{gathered}$

The number is -2/5.
