− 9 h − 6 + 12 h + 40 = 22 ( − 9 h + 12 h ) + ( − 6 + 40 ) = 22 3 h + 34 = 22 ∣ s u b t r a c t 34 f ro m b o t h s i d es 3 h = − 12 ∣ d i v i d e b o t h s i d es b y 3 h = − 4
-9h - 6 + 12h + 40 = 22 3h + 34 = 22 3h = -12 h = -12/3 h = -4
We solved the equation − 9 h − 6 + 12 h + 40 = 22 by combining like terms, isolating h , and finding that h = − 4 .
