I don't see any errors. Raul has the correct steps and final answer. We can check the answer by replacing x with -12 and simplifying the left side

-6x = 72
-6*x = 72
-6*(-12) = 72 ... replace x with -12
72 = 72

Since we get a true equation, we have confirmed the answer is actually x = -12

Do 2/5+5/7 and there's your answer. 2/5+5/7=14/35+25/35=39/35=1 4/35. :)

s344n2d4d5 [400]

Answer:

n = 27

Step-by-step explanation:

14n = 11n + 81 (Given)

14n - 11n = 11n - 11n + 81 (Subtraction Property of Equality)

3n = 81 (Simplify)

$\frac{3n}{3} = \frac{81}{3}$ (Division Property of Equality)

n = 27 (Simplify)
