We have simultaneous equations: \[ x = y + 4 \] and \[ 6y - 4x = 4 \]

Thanks gentoolx. Ok I get that, are they solved separately, or is one solved before the other?

So, you can just substitute the value from first equation (x value) to the second equation or you can transform the first to \[ x-y=4 \] and then: \[4x-4y=16\] Then you sum up these two equations to get \[2y = 20 \] Then you compute value of y and then you substitute it to one of the original equations to compute x.

To be clear: when I meant "these two equations" I meant transformed equation and the second equation from original ones.

Thanks again, I am sorry how do you get the 4 on the other side of the equal sign
anonymous
  • anonymous
you multiplied 4 by both sides
anonymous
  • anonymous
I multiplied both sides by four.

\[x = y + 4\] \[x - y = 4 | * 4\]\[4x - 4y = 16\]
