question :

fine the value of "n" in this equation: 2n + 3 = -6.2

answer :

n = -3.1

explanation :

2 * -3.1 + 3 = -3.2

so you subtract 3 from -3.2 which is -6.2 so now the equation is 2n = -6.2 so what is -6.2 divided by 2? its 3.1 so thats your answer and how to get your answer. i hope this helps for future questions simalar to this one.

-14 is the answer

hope this : ))
