If you answer can you try and do it step by step so I can understand it better :)

Answer 1

the answer is B

`3( (7)/(5) x + 4) - 2( ( 3)/(2) - (5)/(4) x)`

`(3 * (7)/(5) x) + (3 * 4) - 2( (3)/(2) - (5)/(4) x)`

`(21)/(5) x + 12 - 2( (3)/(2) - (5)/(4) x)`

`(21)/(5) x + 12 + ( - 2 * (3)/(2) ) + ( - 2 * ( - (5)/(4) x))`

`(21)/(5) x + 12 - 3 + (5)/(2) x`

`(21)/(5)x + (5)/(2) x + 12 - 3`

`(67)/(10)x - 9`
