What do you mean?

OpenStudy (tkhunny):

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.

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

OpenStudy (anonymous):

wait that's not right

OpenStudy (anonymous):

it would be 6x + 9y = 13

OpenStudy (tkhunny):

The First) 2x+y=5 3xThe Second) -12x+18y=-6 Add them: -10x + 19y = -1 -- That looks pretty good.
