Answer 1

@Butterfly16

Answer 2

Hint:

either distribute to get

4j - 28 = 12

or

divide both sides by 4 to get

j - 7 = 3

Answer 3

Wouldn't it be 4j-28=12

Answer 4

thats one way to go, what do you get when you solve that

Answer 5

Yeah

Answer 6

I add 28?

Answer 7

Yes.

Answer 8

Then divide both sides by 4.

Answer 9

Ok thank you :)

Answer 10

Glad we helped.

Answer 11

7(2p+3)-8=6p+29

Answer 12

14p+21-8=6p+29 ?

Answer 13

good so far

Answer 14

what's next

Answer 15

Subtract 6p?

Answer 16

yep

Answer 17

14p+21-8=6p+29

14p+21-8 - 6p = 29

then what

Answer 18

8p+21-8=29?

Answer 19

good, next step?

Answer 20

Add 8? I don't know

Answer 21

or you can combine 21-8 to get 13

this gives you

8p+13 = 29

then you can subtract 13 from both sides to get

8p = 29-13

Answer 22

Ohh

Answer 23

so 8p = 16

p = ??

Answer 27

3x-9=7.5+5x

Answer 28

Butterfly!! :)

Answer 29

Haha here I am :o)

3x-9=7.5+5x
What do we do first? I know you know it :o)

Answer 30

subtract 5x?

Answer 31

Think of it like this: 3-5 or 5-3? :o)

Answer 32

5-3

Answer 33

-9=7.5+2x

Answer 34

Fantastic! Now, solve for x! Tell me what you do next :o)

Answer 35

add 9?

Answer 36

Nope. Remember, when you take from one side, you must take from the side with the x. So instead, take the 7.5 from the side with the x. :o)

Answer 37

Ohh so -7.5

Answer 38

You got it! :o)

Answer 39

x=-8.25

Answer 40

Great job! I knew you could do it. :o)

Answer 41

a-5/10=2a-3/5

Answer 42

a=1/10

Answer 43

\[\frac{ a-5 }{ 10 }=\frac{ 2a-3 }{ 5 }\]
Cross multiply :o)
\[10(2a-3)=5(a-5)\] Distribute
\[20a-30=5a-25\]\[15a-30=-25\]\[15a=5\]\[a=\frac{ 5 }{ 15 }\]\[a=\frac{ 1 }{ 3 }\]

Do you see how I got that? :o)

Answer 44

Wait which do I cross multiply?

Answer 45

For the original equation, you're first going to cross multiply. So, a-5 times the 5, and then the 2a-3 times the 10.

Answer 46

I'm still not seeing it :/

Answer 47

I have some family coming over in 15 minutes and I have to go with them to town. Will you be on later so we can do this later?

Answer 48

Yup, I'll type up some instructions on that one and message it to you for when you get back. :o)

Answer 49

Ok thank you! Talk t you soon :)
