Solve the eqautions:

9y=4y+55

16+4t=6t

7d+10=4d+16

2k+20=4k+2

Ok so yeah it maybe 2nd year work but I've forgotten how to do them.

More shall probibly be coming soon...

:|:|:|

Thanks :]

1st 1 :
9y = 4y + 55

(-4y) 5y = 55

(/5) y = 11

2nd :

16 + 4t = 6t

(-4t) 16 = 2t

(/2) 8 = t

3rd :

7d + 10 = 4d + 16

(-4d) 3d + 10 = 16

(-10) 3d = 6

(/3) d = 2

4th :

2k+20 = 4k +2

(-2k) 20 = 2k+ 2

(-2) 18 = 2k

(/2) 9 = k

Hope that helps - The stuff in brackets is what I did each time

1. y = 11 because 9y = 4y + 55 [-4y]
5y = 55 [/55]
y = 11

2. t = 8 because 16 / 2 = 8 [ use above rule]

3. d = 2 because u first minus 4d from both sides, then - 10 which gives u
3d = 6 then divide by 3

4. k = 2 i think, cant go into explaining it sorry

Hope these are right . I think they are
Can't beleive I am doing maths for you!!

9y=4y+55
9y-4y = 55
5y= 55
y = 11

16+4t=6t
16= 6t - 4t
16 = 2t
8 = t

7d+10=4d+16
7d -4d = 16 - 10
3d = 6
d = 2

2k+20=4k+2
2k-4k = 2 - 20
-2k = -18
-1k = -9
1k = 9

There. The simple way. And easiest to copy

They were all really helpful and they jogged my mind so I've remembered. Thank you!

[kk.]

no problem

[Dudedanny123]

They were quite easy. We finish equations awhile ago

Have you done linear and quadratic sequences yet at your school??

[kk.]

uhh quadratics, ive heard to much of them lol.
btw thnks for th rep, im now 113

I'm going to pretend I know what you mean No we haven't, we finish equations ages ago and it's all in there somewhere but I'd forgotten. We just finished Pi [or is it Pii?].

[Dudedanny123]

I love PIE
Lol. Chicken Pie.

Oh you mean maths pie lol
Thats boring
are you doing circles or something?
