since we want it in the form Ax+By=C, you basically have to get the x & y terms on the left side get everything else to the right side
So subtract 2x. 2x-y-3=-10
I mean -2x+y-3=-10
good, y-3=2(x-5) y-3=2x-10 -2x+y = -10+3 -2x+y = -7
now some books require A to be positive to do that, we multiply both sides by -1 -2x+y = -7 -1*(-2x+y) = -1*(-7) 2x-y = 7
Then its 2x+y=7?
this step is optional
you forgot to multiply -1 by the +y term to get -y
Thanks for the clarification. 2x-y=7??
yep, assuming the requirement your book/teacher needs A > 0
Yes! Alright thanks for that!
