Answer:
[tex]2x - 14[/tex]
Step-by-step explanation:
Here's the method I would use to rewrite this expression.
Expanding the expression first
[tex]3(x-4) - (x+2) = (3*x - 3*4) - (x + 2) = 3x - 12 - x - 2[/tex]
Now we can sum like terms. We put the variable together and the constants together.
[tex]3x - 12 -x -2 = (3x - x) + (-12 -2)[/tex]
Note the use of the + in this expression. This is because subtracting a term is the same as adding the negative of that term.
[tex](3x - x) + (-12 -2) = 2x + (-14) = 2x - 14[/tex]
