Answer:
36+19x
Step-by-step explanation:
Ok, first, combine like terms, so the two values with X.
42 + 7x + 12x – 8
42 +19x – 8
Now, we combine the two values that have no X
42+19x– 8 Imagine there is a plus sign in front of the 42 because it's positive.
So 42-8=36
36+19x
That's your solution, that's the most this can be simplified.
