Question

If AB=8x-7, BC=4x+9, and AC=13x-2, For what vallue of x are AB and BC congruent?

Answer 1

If we want AB and BC to be congruent, then we want AB = BC to be true

Answer 2

So this means we want

8x-7 = 4x+9

to be true. Solve this for x to get your answer.

Answer 3

so X=4 do I have to plug it into anything?

Answer 4

They just want the value of x (and not AB, BC or AC). So you're done.

Thanks!
