Hint: either distribute to get 4j - 28 = 12 or divide both sides by 4 to get j - 7 = 3
Wouldn't it be 4j-28=12

thats one way to go, what do you get when you solve that
Yeah
I add 28?
Yes.
Then divide both sides by 4.
Ok thank you :)
Glad we helped.
7(2p+3)-8=6p+29
14p+21-8=6p+29 ?
good so far
what's next
Subtract 6p?
yep
14p+21-8=6p+29 14p+21-8 - 6p = 29 then what
8p+21-8=29?
good, next step?
Add 8? I don't know
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
Ohh
so 8p = 16 p = ??
2
you got it
:)
3x-9=7.5+5x
Butterfly!! :)
Haha here I am :o) 3x-9=7.5+5x What do we do first? I know you know it :o)
subtract 5x?
Think of it like this: 3-5 or 5-3? :o)
5-3
-9=7.5+2x
Fantastic! Now, solve for x! Tell me what you do next :o)
add 9?
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)
Ohh so -7.5
You got it! :o)
x=-8.25
Great job! I knew you could do it. :o)
a-5/10=2a-3/5
a=1/10
\[\frac{ a-5 }{ 10 }=\frac{ 2a-3 }{ 5 }\] 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)
Wait which do I cross multiply?
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.
I'm still not seeing it :/
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?
Yup, I'll type up some instructions on that one and message it to you for when you get back. :o)
Ok thank you! Talk t you soon :)
