Best ResponseYou've already chosen the best response.0We have simultaneous equations: \[ x = y + 4 \] and \[ 6y  4x = 4 \]

Best ResponseYou've already chosen the best response.0Thanks gentoolx. Ok I get that, are they solved separately, or is one solved before the other?

Best ResponseYou've already chosen the best response.0So, you can just substitute the value from first equation (x value) to the second equation or you can transform the first to \[ xy=4 \] and then: \[4x4y=16\] 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.

Best ResponseYou've already chosen the best response.0To be clear: when I meant "these two equations" I meant transformed equation and the second equation from original ones.

Best ResponseYou've already chosen the best response.0\[x = y + 4\] \[x  y = 4  * 4\]\[4x  4y = 16\]
