Respuesta :

We have the equation 2-(k+4)=3.

The variable is k, because is the only unknown number. Solving for k:

[tex]\begin{gathered} 2-(k+4)=3 \\ 2=3+(k+4)=3+4+k=7+k \\ 2-7=k \\ -5=k \end{gathered}[/tex]

The variable has the following operations:

• Add 4

,

• Multiply by (-1)

,

• Add 2

The inverse of the last thing is Subtract 2, subtract is the opposite of add.
