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

You can put this solution on YOUR website!
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

1m = 8-6

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

Your answer is Correct.


No need of any correction
