Question 65527: This is like a disscussion question. Problem 51 on Page 512:
You now have had practice soving equations with one variable and equations with two variables. Compare equations with one variable to equations with two variables. How are they alike? and how are they different?
I think that the comparisons of equations with one and two variables have similarities because you have an unknown figure, which you would need to use algebraic formulas by either multiplying, dividing, adding, or subtracting to get the unknown figure. They are different in the ways in which they are treated to get the unknown number.
Then my instructor threw in an additional question to answer: What if an equation had three variables?
I am not quite sure how to answer this question. I am not even sure I am on the right track with the questions I answered above. Could you give some assistance please. Thanks.

Question 65675: Can someone correct this for me.
Find values for m and b in the following system so that the solution to the system is (1,2)
Mx+3y=8
-3x +4y = b
---------------------------------
m (1) + 3(2) = 8
1m + 6 = 8
-6 -6
1m = 2
1m/1 = 2/1
m = 2
-----------
-3(1)+ 4 (2) =b
-3+ 8 = b
5 = b
so the values are: m = 2 and b=5

Question 65939: Now i have an equation which is :
3x = 3x + 5
which I know has no solution to it,
now whereas the equation 7x + 8 = 8 has zero as a solution.
What is the difference between a solution of zero and no solution?
