I don't know about the first one but for the second one:

{2}^{3x + 2}  -  {2}^{3x}  = 48 \\ \Leftrightarrow {2}^{3x}  {2}^{2}  -  {2}^{3x}  = 48 \\ \Leftrightarrow  {2}^{3x} ( 4  - 1) = 48 \\ \Leftrightarrow 3 \times  {2}^{3x}  = 48 \\ \Leftrightarrow  {2}^{3x}  = 16 \\ \Leftrightarrow  {2}^{3x}  =  {2}^{4}  \\ \Leftrightarrow 3x = 4\Leftrightarrow x =  \frac{4}{3}
