Question

3x+y=4

6x+2y=8

Use the system of equations to solve. Please explain or show how you got the answer!

Answer 1

3x + y =4 6x + 2y=8
-3x -3x -6x -6x
y=-3x+4 2y= -6x+8
*divide everything by 2
y= -3x+4
you have to get it into y=mx+b form

*drop the y from both problems and use from x and back for both problems

-3x+4= -3x+4
+3x +3x

4=x+4
-4 -4

1/1 = 1/1
x=1
