Question

the sum of twice a number and five is 11 . find the number?

Answer 1

Solution

Let the number be represented by x

$2x+5=11$

Now, solve x

$\begin{gathered} 2x=11-5 \\ 2x=6 \\ divide\text{ both sides by 2} \\ \frac{2x}{2}=\frac{6}{2} \\ \\ x=3 \end{gathered}$

The final answer

The number is 3

$x=3$
