Distributive property and combine like terms:
9h-7h-7+4h-12
2h+4h-7-12
6h-19
Hope this helps!

9h -7(h+1) + 4(h - 3) = 0
9h - 7h -7 + 4h -12 = 0
(9h - 7h + 4h) -7 -12 = 0
6h - 19 = 0
6h = 19
h = 19/6

9h - 7(h + 1) + 4(h - 3)
9h - 7h - 7 + 4h - 12 - -Distributive property
9h - 7h + 4h - 7 - 12 - -Collecting like terms
6h - 19
The answe is 6h - 19

Is this an equation or just an expression??
anyway,
the given expression
=9h-7h-7+4h-12
=6h-19
if it is an equation (equal to zero, i suppose)
6h-19=0
h=19/6

=9h-7h-7 + 4h-12
= 2h - 7 + 4h - 12
= 6h - 19

expand 7(h+1) and 4(h-3). which makes 9h-7h-7+4h-12= 6h-19
6h-19=0
6h=19
h=3.1666666..

That simplifies to 9h^2 - 2h -19. That looks like a quadratic equation, but since you didn't say what it equals, I can't solve it.
