Question

How do the problem h-6+7h=42

Answer 1

$h-6+7h=42 \\\\ 8h-6=42 \\\\ 8h=42+6 \\\\ 8h=48 \\\\ \boxed{h=\frac{48}{8}=6}$

Answer 2

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
