Answer:
n = -9
Step-by-step explanation:
-3 (n + 5) = 12 Use the distributive property (-3 · n) + (-3 · 5) = 12
-3n - 15 = 12 Add 15 to both sides
-3n = 27 Divide both sides by -3
n = -9
Check your answer by plugging -9 in for n.
-3 (n + 5) = 12 Replace n with -9
-3 (-9 + 5) = 12 Add
-3 (-4) = 12 Multiply
12 = 12
