Question 692934: please solve this
3x+y=6
4x+2y=8
Answer by ankor@dixie-net.com(22740) (Show Source): You can put this solution on YOUR website!
3x + y = 6
4x +2y = 8
multiply the 1st equation by 2, subtract the 2nd equation
6x + 2y = 12
4x + 2y = 8
--------------subtraction eliminates y, find x
2x = 4
x = 4/2
x = 2
:
Find y using the 1st equation
3(2) + y = 6
6 + y = 6
y = 6 - 6
y = 0
:
:
Check the solutions in the 2nd equation
4x + 2y = 0
4(2) + 2(0) = 8
