Answer 2

If you can manipulate one to create the other, then you are done. Please try the given instructions and see how close you get.

Answer 3

What do you mean?

Answer 4

Read the instructions.

"by adding the first equation to two times the second"

The First) 2x+y=5
2xThe Second) -8x+12y=-4

Add them: -6x + 13y = 1

That does not look familiar. Move on to the next one.

Answer 5

Ok. So the first equation added to the second equation of system A 3 times would be 2x + 7y = 3

Answer 6

wait that's not right

Answer 7

it would be 6x + 9y = 13

Answer 8

The First) 2x+y=5
3xThe Second) -12x+18y=-6

Add them: -10x + 19y = -1 -- That looks pretty good.
