Hannah is solving the equation $4\left(x-3\right)=16$ . Her first step shows  $4x-12=16$ .

Which step could be the next step. Select all that apply.

•  $4x-12+12=16+12$  

•  $4x-12-\left(-12\right)=16-\left(-12\right)$  

•  $4\left(4x-12\right)=4\left(16\right)$  

•  $\frac{4x}{4}-12=\frac{16}{4}$  

•  $4\cdot\left(4x-12\right)=16\cdot4$
