The number is $- 1$

#### Explanation:

Use the information give to write an equation and solve it.

Let the number be $x$

'Twice a number' means $2 \times x = 2 x$

'$4$ more than twice a number' means: $2 x + 4$

The answer to this must be $2$. Show it as:

$2 x + 4 = 2 \text{ } \leftarrow$ now solve the equation you have written.

$2 x + 4 \textcolor{b l u e}{- 4} = 2 \textcolor{b l u e}{- 4}$

$2 x = - 2 \text{ } \leftarrow \div 2$

$x = - 1$

Check: $\left(2 \times - 1\right) + 4 = 2$
