First there are 4 steps .
First step: Isolate the variable
Second step: Reverse the operations
Third step: It become's a zero pair, and then the variable is isolated by itslef so you solve the question.
Fourth step: Rewrite the question and check your answer.
First Question: A+4=10
A+4-4=10-4
10-4=6
Check it :
10+4= 10
6+4=10
10=10 .
A= 6.
Second Question:
B-2=5
B-2+2=5+2
B=7
Check it.
B-2=5
7-2=5
5=5
B=7
Third Question: / = Divided
W/3=6 ( divided)
Wx3=6x3
6x3=15
Check it.
W/3=6
18/3=6
6=6
W= 18.
Fourth Question: / = Divided , brackets means multiplying.
3C=21
3/3=21/3=7
Check it.
3C=21
3(7)=21
21=21
C=7
Fifth Question: / = Divided
F/3-2=1
F/3+2+1+2
Check it.
F/3-2=1
1+2=3
9/3-2=1
3-2=1
1=1
F= 9.
Sixth Question: / = Divided. brackets means multiply.
2J+1=9
2J=1-1+9-1.
2/2=8/2
Check it.
2J+1=9
2(4)+1=9
8+1=9
9=9
J=4.

Wow great post Angelika! Thanks, this helps me a lot!
And when I get stuck again, ill come to see your post. But a video and a picture would be nice. Maybe a link too. Thank you!
nice job Angelika! i like how you used different colors to make the words stand out but next time you add a link or video and maybe a picture to but otherwise good job!
good job but you shouldn't use so many colors because it hurts my eyes plus you should add a video or link
good job angelika! i like how you used different coulrs to make the words stand out too. but maybe next time you should add a liknk and a video to help people more if they still dont understand it.
oh and maybe this video will help http://www.youtube.com/watch?v=yAHonwohXBk&feature=player_embedded#at=82
Good job Angelika. The colors help the words stand out very well. And you can really tell the difference between the question. But next time you should add a link for others to visit. I think this might help : http://ca.ixl.com/math/grade-7/does-x-satisfy-the-equation
Thanks for all the comments and no problem! I will try to add a link/ video next time .
Great job! I liked how you used all of those wonderful colours. But you should try adding a link or maybe a video or both and that would help me more!
Great job! I like that way you used lots of colors. and if you're going to do the blog again, next time try to put a link and also try adding a video, but nice job.
good job Angelika! love the colours you did really good keep up the good work
Awesome job Angelika! i love how you used a lot of colors to make the words stand out. Next time add a video or a link.
Great job Angelika! i like how you used alot of colour it really caught my attention and made me want to read your blog. Your information is very good and it helped me study, But maybe next time to make it even more better add a link or video, maybe even add some pictures to show exactly how you are doing the math equation because it was kindve hard to understand what you got and how you got your answer. great job though
