Question

75=3(-6n-5)

Having troubles with this one too!! XD. I’m going to fail math this year, I swear ;((

Answer 1

75 = 3 (-6n - 5)
75 = -18n - 15
75 + 15 = - 18n
90 = -18n
90 / 18 = -n
5 = -n
-5 = n

check:
75 = 3 (-6 (-5) - 5)
75 = 3 (30 - 5)
75 = 3 × 25
75 = 75

Answer 2

Distribute.
3(-6n-5)=75
-18n-15=75
-18n=75+15
-18n=90
n=90/-18
n=-5
