Step-by-step explanation:

 \frac{3x}{10}  + 12 =  \frac{4x}{10}  - 28 \\  \frac{3x + 120}{10} =  \frac{4x - 280}{10}   \\ 3x + 120 =  \cancel{10} \times  \frac{4x - 280}{ \cancel{10}}  \\ 3x + 120 = 4x - 280 \\ 3x - 4x =  - 280 - 120 \\   \cancel- x = \cancel  - 400 \\  \purple{ \fbox{ \red{x = 400}}} \\  \\
