Question

Solve both in substitution and elimination: HELP!!!
3x+2y=8
2x+y=6
Graph you results.

Answer 1

multiply 2x+y=6 by 2 and subtruct from equation 1
x will be equal to 2 now sustitute x=2 in equation 1
y=3%2

Answer 2

That's wrong.
3x+2y=8
2x+y=6
Substitution Method:
2x+y=6
-2x -2x
-----------------
y=-2x+6
Plug that in to 3x+2y=8
So, 3x+2(-2x+6)=8
3x-4x+12=8
----------------
-1x+12=8
-12 -12
---------------
-4/-1x
x=4

Answer 3

The you plug "x" into the top equation:
3(4)+2y=8
12+2y=8
-12 -12
--------------
-4/2y
y=-2
Answer:
(4,-2)
