What is 8 equals 14 plus x?

Answer 1

First, to simplify and show you a easy way to do negative variable problems, multiply both sides, all terms, by a negative 1.

-1(-X + 8 = 14)

X - 8 = -14

add the 8 to both sides

X = -6

check in original equation

-(-6) + 8 = 14

that negative times a negative makes the 6 positive

6 + 8 = 14

14 + 14

checks

Answer 2

X= -6.
