I'm dyslexic and need help with math help?

Question

I have a very smart couzin. she's 10 and already in algebra thats 9th grade math!!! lol i'm 16 and i'm watching her she asked me to check her math homework and i'm dumb lol well dyslexic and it's hard for me to check the answers and the work!!! i'm pretty sure i have it right but i'm not positive if anyone would find it there hearts to not make me look stupid infront of my aunt. we are not very close and she might stop letting me babysit. And i really need the money...

math problems

1) 8x - 16+8x=16

2) 7c - 8 - 2c=17

3) 6= - y+42 - 2y

4) 16+8r-4r+4=24

5) 7 - 4c=3c-7

6) f - 4=6f=26

7) - 2s+3=5s+24

8) 5d - 3=8a+6

9)8n - 12= - 12n+8

10) 7y+8= -2y -64

Answer 1

1) 8x - 16+8x=16

16x - 16 = 16

16x = 32

x =2

2) 7c - 8 - 2c=17

5c =  25

c = 5

3) 6= - y+42 - 2y

6 = -3y +42

-36 = -3y

12 = y

4) 16+8r-4r+4=24

20 + 4r =24

4r = 4

r = 1

5) 7 - 4c=3c-7

-7c = -14

c = 2

6) f - 4=6f + 26

-5f = 30

f = -6

7) - 2s+3=5s+24

-7s = 21

s = -3

8) 5d - 3=8a+6

-3d = 9

d = -3

9)8n - 12= - 12n+8

20n = 20

n=1

10) 7y+8= -2y -64

9y = -72

y = -8

Answer 2

I hope your Aunt becomes more understanding of your abilities.  Algebra isn't too hard - it just takes some concentration and you have to check your work a few times.  Good luck!

1)

8x - 16 + 8x = 16   ...8x + 8x = 16x

16x - 16 = 16   ...add 16 to both sides

16x = 32   ...divide both sides by 16

x = 2

2)

7c - 8 - 2c = 17   ...7c - 2c = 5c

5c - 8 = 17   ...add 8 to both sides

5c = 25   ...divide both sides by 5

c = 5

3)

6 = -y + 42 - 2y   ...-y - 2y = -3y

6 = 42 - 3y   ...subtract 42 from both sides

-36 = -3y   ...divide both sides by -3

12 = y

4)

16 + 8r - 4r + 4 = 24    ...8r - 4r = 4r

16 + 4r + 4 = 24   ...16 + 4 = 20

4r + 20 = 24   ...subtract 20 from both sides

4r = 4   ...divide both sides by 4

r = 1

5)

7 - 4c = 3c - 7   ...add 7 to both sides

14 - 4c = 3c   ...add 4c to both sides

14 = 3c + 4c  

14 = 7c   ...divide both sides by 7

2 = c

6) I don't know what to do with 2 equal signs, I think you wanted one of them to be a plus sign but I'm not sure which one.

7)

-2s + 3 = 5s + 24   ...subtract 24 from both sides

-2s - 21 = 5s   ...add 2s to both sides

-21 = 5s + 2s

-21 = 7s   ...divide both sides by 7

-3 = s

8) You have two variables here, a and d.  Which one do you want to solve for?

9)

8n - 12 = -12n + 8   ...add 12n to both sides

8n + 12n - 12 = 8   ...add 12 to both sides

8n + 12n = 20

20n = 20

n = 1

10)

7y + 8 = -2y - 64   ...subtract 8 from both sides

7y = -2y - 72   ...add 2y to both sides

7y + 2y = -72

9y = -72   ...divide both sides by 9

y = -8

Hope this helps you!
