It's All Greek To Me. I get most of it, but I forgot how to do open sentences; Well, The Division part. Let Me Show You What I Mean:

36/b - 3 = 0

46 - 15
---------- = a
3 + 28

It has been a long time for me, but can show a primitive meathod.
The first one is a number that equals 3, since it has a minus 3, start with 3.
what number would go under or be divisible by 36? 1/3 of 36 is 12. 36 over 12 is 3. 3-3=0.
2nd problem, again primitive, 15 from 36 is 31,
and 3+28 is 31,
31 over is 31 equals 1, but not for sure, if this is a test, don't want to be responsible.

$\frac{36}{b} - 3 = 0$

This means 36 divided by some number, then, if you remove 3, you have to get zero. When do you get a zero by subtracting 3? When that number is also 3, so that 3-3 = 0. That means that $\frac{36}{b} = 3$ . I'll let you guess that one.

The 'good' method is;

$\frac{36}{b} - 3 = 0$

Add three on both sides;

$\frac{36}{b} - 3 +3= 0+3$

$\frac{36}{b}=3$

Whatever you do on one side, do the same on the other, that's the principle of solving equations with a variable.

Hope it helped! :)

I thought it was against the rules to do their homework?

If I helped his Homework, I appologize, I did want him/her to understand How to Figure.
As did Unknown008 I'm sure.
