Best ResponseYou've already chosen the best response.0Let's look at option A. 2x + 3 = 8x  3 `I'll add 2x to each side` 3 = 10x  3 `I'll add 3 to each side` 6 = 10x Hmm this is NOT going to lead to a solution of x=0, which is what we want.

Best ResponseYou've already chosen the best response.0Do you think you can try the other options? :o Solve for x in each case.

Best ResponseYou've already chosen the best response.0Oh that was a sloppy method of doing that actually :\ That's going to only narrow it down to two options. I guess a better way to do it would be... plug in x=0, and see which equation gives you 3 = 3.

Best ResponseYou've already chosen the best response.0okay let me try doing it that way can you show me an example please

Best ResponseYou've already chosen the best response.0For Option A, \(\large\rm 2x + 3 = 8x  3\) We know that the point of intersection is at (0,3), so I'll plug in this x coordinate of 0, and it should give us 3 as a result on both sides, \(\large\rm 2(0)+3=8(0)3\) Which simplifies to \(\large\rm 0+3=03\) And since \(\large\rm 3\ne3\), this is not the correct option for us.

Best ResponseYou've already chosen the best response.0Yay good job \c:/ Notice that using the first method I explained.. Would have given you option B as a correct choice, so that was no beuno. This worked out much better! :)
