<PRE><B>Question 626818</B>
elimination method for solving
 A + 8B = 12
 A + 3B = 2
----------------subtraction eliminates A find B
0 + 5B = 10
B = 10/5
B = 2
:
Use the 1st equation to find A, replace B with 2
A + 8(2) = 12
A + 16 = 12
A = 12 - 16
A = -4
:
:
Check solutions in the 2nd equation
A + 3B = 2
Replace A and B
-4 + 3(2) = 2
-4 + 6 = 2</PRE>
