Question

solve solution using elimination
2x+4y=22
2x-2y=-8

Answer 1

multiply one of the equations through by -1
add them together
the X term will cancel out 2x-2x=0

Answer 2

2x+4y=22
2x-2y=-8 multiply second by -1
---------------

2x + 4y = 22
-2x + 2y = 8 add together
--------------
6y = 30

solve for y, then use that y, and solve for x

Answer 3

see that ok?

Answer 4

y=5

Answer 5

right, i mean, how you got to that point, the work

Answer 6

by elimination

Answer 7

right of course, i mean do you understand the process that was carried out in order to 'eliminate' one of the variables?
