-3x-8=19 -3x-2=25 A. The equations have the same solution because the second equation can be obtained by subtracting 19 from bot
h sides of the first equation. B. The equations have the same solution because the second equation can be obtained by adding 6 to both sides of the first equation. C. The equations have the same solution because the second equation can be obtained by subtracting 6 from both sides of the first equation. D. The equations do not have the same solution because the second equation can be obtained by adding 6 to both sides of the first equation.
, you have to factor it as 
, not 
, because that will leave an extra 6x because of 8x - 2x.
