h − 6 + 7 h = 42 8 h − 6 = 42 8 h = 42 + 6 8 h = 48 h = 8 48 = 6
solve for h by isolating it on one side and ask else on the other . . .
h - 6 + 7h = 42
h + 7h - 6 = 42
h(1 + 7) - 6 + 6 = 42 + 6
8h = 48
8h/8 = 48/8
h = 6
To solve the equation h − 6 + 7 h = 42 , we combine like terms to get 8 h − 6 = 42 . After isolating h and solving, we find that h = 6 .
