Answer:
The correct answer is n = -9.
Step-by-step explanation:
-13n + 20 = -11n + 38
20 = -11n + 38 + 13n Add 13n to both sides
20 = 2n + 38 Combine like terms
20 - 38 = 2n Subtract 38 from both sides
-18 = 2n Simplify
-9 = n Divide both sides by 2
OR
-13n + 20 = -11n + 38
-13n = -11n + 38 - 20 Subtract 20 from both sides
-13n = -11n + 18 Combine like terms
-13n + 11n = 18 Add 11n from both sides
-2n = 18 Simplify
n = -9 Divide both sides by -2
