Can someone simplify it or expand it please I need it in like 5 mins !

Answer 1

`=\tt x - 3 + 7(x + 3) - 3x - 12`

`=\tt x - 3 + 7x + 21 - 3x - 12`

`=\tt 7x + x - 3x - 3 - 12 + 21`

`=\tt 8x - 3x - 15 + 21`

`\color{plum}=\tt\bold{ 5x + 6}`

▪︎Therefore :

`\color{hotpink} =\tt x - 3 + 7(x + 3) - 3x - 12 \color{plum}=\tt\bold{ 5x + 6}`
