For this case we have to simplify the following expression:
[tex]12x + 3 - 4x + 7 =[/tex]
We combine similar terms:
[tex]12x-4x + 3 + 7 =[/tex]
Taking into account that equal signs are added and the same sign is placed, and different signs are subtracted and the sign of the major is placed. So:
[tex]8x + 10[/tex]
So, [tex]8x + 10[/tex] is the most simplified form.
Answer:
[tex]8x + 10[/tex]
