Simultaneous Equations

[JoeComins]

I know the answer, but I need the working out for the following:

3V-2=-4W and W=4V-28

Thanks

2 = 4W + 3V 112=19V
-112 = 4W - 16V 6=V

So W = -4

I know thats the right answer, but could you explain it a little clearer?

[Catchetat]

ok I arranged your equations and made them have the same "factor"

so I changed from your 3v-2 = 4W to 2 = 4W+3v (1)

I did the same with your other equation: w= 4v-28 to -112=4w-16V (2)

Notice the 4ws are the same

So all you ahve to do now is (1)-(2)

which leads to 114=19V so v = 6

Replace v=6 to any equation and u get w=-4
