-2H = 28
H = -14
6(-14) - 8(-14) + 9 = 37
-84 + 112+ 9 = 37
28 + 9 = 37
37 = 37

6h-8h+9 = 37
-2h = 37-9
-2h = 28
h = 28/-2 = -14
Check: (6*-14) - (8*-14) + 9 = -84 - (-112) + 9
= -84 + 112 + 9 = 37
Solved.

6h-8h+9=37
-2h+9=37
-2h=28
h=-14
check:
[6(-14)] - [8(-14)] + 9=37
-84 - [-112] + 9=37
-84 + 112 + 9=37
28 + 9=37
37=37

6h-8h+9=37
You add the 6+8 together then you make it a 13h-9=37 you plus the 9 to 37=42 then you divide that by 13 which is a no

6h -8h + 9 = 37
Group the h's together
6h -8h = -2h
therefor;
-2h + 9 = 37
subtract 9 off each side
-2h +9 -9 = 37 - 9
-2h = 28
Divide by two
-h = 14
Multiply each side by (-1)...[Remeber, what you do to one side, do to the other]
h= -14
Check
6(-14) - 8(-14) = 37
-84 - (-112) = 37
-84 + 112 = 37
37 = 37

6h - 8h + 9 = 37
-2h + 9 = 37
-2h = 37 - 9
-2h = 28
-2h / -2 = 28 / -2
h = -14

6h-8h+9=37
-2h=37-9
-2h=28
-2h/-2=28/-2
(cancel both -2)
h=-14
check: 6(-14) - 8(-14) + 9
-84 +112 + 9
37 :D

It looks correct to me. I believe 37 is your answer. I think to check this you need a calculator to be sure.

first u subtract 9 from 37....
then you get -2h=28
divide both sides by -2
you end up with h=-14
