3(X-5)=27. 3x-15=27. 3x=42. X=14. It looks like they tried to add 5 instead of multiplying it, and they added 5 and 27 wrong. :)

How to solve it step by step <br> -8+4(1+5n)=-6n-14
oksano4ka [1.4K]

Answer:

n = -5/13

Step-by-step explanation:

-8+4(1+5n)=-6n-14  (from PEDMAS, expand parenthesis first)

-8+1(4) +5n(4)=-6n-14

-8+4 +20n=-6n-14

-4 + 20n = -6n -14  (add 6n to both sides)

-4 + 20n + 6n =  -14

-4 + 26n = -14  (add 4 to both sides)

26n = -14 + 4

26n = -10  (divide both sides by 26)

n = -10/26 = -5/13
