Simplify the following expression and write the final answer in standard form. ( 20 x y + 13 x ) − ( 3 x − 12 ) \left(20xy+13x\right)-\left(3x-12\right) ( 2 0 x y + 1 3 x ) − ( 3 x − 1 2 )

20 x y + 10 x + 12 20xy+10x+12 2 0 x y + 1 0 x + 1 2

20 x y + 10 x − 12 20xy+10x-12 2 0 x y + 1 0 x − 1 2

20 x y + 16 x + 12 20xy+16x+12 2 0 x y + 1 6 x + 1 2

20 x y + 16 x − 12 20xy+16x-12 2 0 x y + 1 6 x − 1 2

36 x y + 12 36xy+12 3 6 x y + 1 2
