Answer:
the answe is -4
Step-by-step explanation:
first you distribute the five to the numbers in the paranthesis
5(-2n+6)
-10n+30=70.
than we subtract 30 from the 30 and 70
-10n=40
Next we divide by 10 to 40 and -10n
n=-4
the reason it negative is because if you divide a negative and a positive it always make a negative.
