For this case we must simplify the following expression:
[tex]7(x-2) -4x+ 9[/tex]
We apply distributive property to the terms within parentheses:
[tex]7x-14-4x+ 9[/tex]
We add similar terms taking into account that:
Equal signs are added and the same sign is placed.
Different signs are subtracted and the major sign is placed.
[tex]7x-4x-14+9[/tex]
[tex]3x-5[/tex]
Answer:
[tex]3x-5[/tex]
