but how would I go about it in this case?
what would the solution be like?
In this case, substitute the expression 3x + 2 into the first equation to get: 6x - 2(3x + 2) = -4 Then simplify and isolate x. Afterwards, find the value of y.
thx but look here: http://www.wolframalpha.com/input/?i=6x+-+2%283x+%2B+2%29+%3D+-4
is it Inconsistent? Dependent? or are the coordinates? what would the answer be like? thx so much!
Actually, the first thing I usually do before using any method is to simplify equations when necessary. We can simplify the first equation. When we do that we get: 3x - y = 2 That can be manipulated to get 3x + 2 = y Which so happens to be the same line as the second equation. So no need to use substitution method since both equations are actually the same.
so which coordinate would that be? or would it be Inconsistent or Dependent? thx by the way for your time. :D
Keywords: "since both equations are actually the same. "
so Inconsistent or Dependent?
Inconsistent is like... x+y = 1 and x + y =5 Dependent is like... x+y = 1 2x + 2y= 2 Any guess?
Nope I'm bricked... :( Can you PLEASE provide the response! :(
what's the graphing lines? what's the coordinates? or is it dependent? or inconsistent?
