Connor: My Schoolwork
Today I learned about using the fraction bar for division in algebra. The way you do it is you divide and then add or subtract. Or you can add or subtract then divide. Algebra is a very interesting part of math. I was also playing Lego Indiana Jones for the Wii with Mason this morning. Wii had lots of fun. I would like you to try to solve this equation 9(x+5)= 810 what does x equal?

Does x=85?
85 is right. But nana gets no points because she didn't show her work. Here's the original equation:
9(x+5)=810
To begin to isolate x, the first thing I'll do is divide both sides by 9, cancelling out the 9 on the left side:
x+5=810/9
OR
x+5=90
Then we subtract 5 from both sides:
x=85
85!
You were both correct so here is a new equation x+222
_____
3 = 12 what is x
