Ok. 

 

x= -2, so you substitute the x for a negative 2. You then multiply -2 by -3, since a variable next to a coefficient signals multiplication. -2 times -3 is equal to positive 6. You then take that positive 6 and multiply it by -7. Negative times positive equals negative, so the answer is -42.
