Answer:
6. 5x+15
Step-by-step explanation:
Distributive property would be the first thing to do, so
-3(2x-5+x)
-6x + 15 -3 x
12x-6x-5-3x+2x
Combine all like terms which are, 12x-6x=6x-3x=3x+2x=5x, and the positive fifteen doesn't have any like terms so we leave that just as it is
5x+15 should be the answer
