Prealgebra help? thanks :]]]?

Question

h-6+7h=42 ...

i got h= 6.85 but i know its not right...

if you could go step by step that'd be great :]

thanks!

Answer 1

h+7h=48    (add 6 to each side)

8h=48       (add the h's)

h=6          (divide each side by 8)

Answer 2

first you add six to both sides and then you subtract h from 7h then you divide both sides by six

Answer 3

first add the like terms

8h-6=42 than add 6

8h=48

then divde by 8

h=6

Answer 4

h-6+7h=42

h + 7h = 48 (by adding 6 to both sides)

8h = 48 (by combining like terms, h + 7h)

h = 48/8 (divide both sides by 8 to get h on its own)

h = 6

Answer 5

h-6+7h=42

h+7h=42+6

8h=48

h=48/8

h=6

Answer 6

h=6

Answer 7

h-6+7h=42    

h+7h=42+6    (Add like terms.)

8h=48

Divide by 8 on both sides and you get...

h=6

Answer 8

h equals 6-6=0 and 6*7=42  

Answer 9

ok first you do change h-6 to h+ negative 6 (it's the same thing as h-6) then u add 6 to negative 6 and 42 (this takes away the 6) 42 becomes 48. then u add the 7h and h together( just think of the h as a 1h it's the same thing h=1h) so 7h becomes 8h. then u divide 42 and 8 and you get h=6 (i hoped this helped!!)  

Answer 10

Good try! The answer is n=6

First, consolidate like terms by adding h+7h:

h-6+7h=42

-6+8h=42      

Now, add 6 to each side of the equation to isolate the variable:

8h=48            

Finally, divide each side by 8:

h=6

Answer 11

ok since you have 2 like terms (h) on one side of the equation, you can add them together. 7h+h= 6h. not that hard. ok so then you're left with 8h-6=42. add six to both sides of the equation. 8h=48. divide each side by 6 to isolate the variable. so you get 6. :)

Answer 12

You add the positive h's to get 8h

then add the 6 to both sides

divide each side by 8

the answer is h=6

Answer 13

h-6+7h=42   combine like terms [the h's]

-6+8h=42 add six to both sides

8h=48 divide by 8  on both sides

h= 6

Answer 14

h-6+7h=42

  +6        +6

h+7h=48

8h=48

h=6

Answer 15

first combine the like terms. since h and 7h are both positive, you add them to get 8h. so its now 8h-6=42. now add 6 on both sides to cancel out the -6 so you get 8h=48. then divide each side by 8 to get h=6. hey you actually were pretty close

Answer 16

It's been a while since i've done algebra, because I had Geometry last year, but I'll try to help. =]

First combine the "h"s, so that you have 8h-6=42, then add the 6 to the 42, to get 8h=48, then divide 48 by 8, and you should have your answer!  I hope I helped, and did this right!  Feel free to blame me if it's wrong ;]

Answer 17

h-6+7h=42

(h+7h)-6=42 (rearranged the equation)

8h-6=42 (added the h values)

8h=48 (added 6 to both sides)

h=6 (48 divided by 8)

Answer 18

h-6+7h=42

h+7h-6=42 (Move the h's next to each other and then combine them)

8h-6=42 (Now add 6 to both sides of the equation:

8h-6+6=42+6

8h=48 (Now divide both sides by 8)

8h/8=48/8

h=6

Answer 19

It's 6

6 - 6 + 7 * 6 = 42

Answer 20

(h+7h)-6=42

8h-6=42

8h-6+6=42+6

8h=48

8h/8=48/8

h=6

Answer 21

h-6+7h=42

simplify left side

8h-6=42

*add 6 to both sides

8h=48

*divide both sides by 8

h=6
