The answer is B. -6. First, you multiply everything inside the parenthesis by the 2 that’s on the outside. Now you have 2n + 10 = -2. Subtract the 10 from both sides. You then have 2n = -12. Divide the 2 from the n on both sides in order to isolate your variable. You are left with your answer, n = -6. Hope this helps. :)

Answer: -6

Step-by-step explanation: use the distributive property and distribute the two to the n and 5. that’ll leave you with 2n+10=-2. then you subtract 10 from both sides and get left with 2n=-12. and then to get the exponent by itself, you divide by two on both sides. and then you’re left with n=-6 :)
