Question 638214: Solving System of Linear Equations by Elimination. My math this week shows an example and I do not understand where the answer comes from. I will provide the example and show where I got lost.
2a + 3b = 25
-2a + b = 11
I understand this section
2a + 3b = 25
-2a + b = 11
--------------
4b = 36
___ ___
4 4 = b=9
2a + 3(9)= 25 <----- this is where my confusion is: the answer it shows it as -1 BUT HOW DID IT GET THIS ANSWER?
I get the fact that it is a point, I see that the answer is (-1,9) but I do not know how to get the -1, I do know where the 9 came from but not the -1.
I hope this is example enough for help. I have similar questions that I have due but I cannot find out the correct answer if I am missing this one step.

I did one with out the example and came to the same problem of finding one point but not the other. I got it wrong because of that one missing part. I will also show what I did.
6a + 5b = 17
-6a + b = 25

6a + 5b = 17
-6a + b = 25
_____________
6b = 42
___ ___
6 6 which is b = 7
6a + 5(7)=17.....AGAIN I AM STUCK! the correct answer was -3 but I do not see how?

Also is there a easier way of doing this math?

Question 638465: The method of substitution to solve the system of linear equations.
3x-y=3
7x-2y=9
I think i am suppose to first get y by it self
y=3x-3
then I am suppose to divide 3 from both sides?
y=3x/3-3/3
I think this is it..
y=3x-3
7x-2y=9
get y on the other side
2y=7x-9
am I suppose to subtract 2 from both ends?
y=7x-?
I am lost form here.
