Hi i have the following problem..
0.00243 = 200/E - V/E (100)
0.00057 = 100/E - V/E(200)
I have been asked calc E & V from the equations.. I've tried sbstitution to solve it but I cannot seem to isolate any 1 of the vairables
3x + 4y = 1
6x - 2y = 5
you can solve this by multiplying the 1st equation by 2 and then subtract the 1st equation with the 2nd
6x + 8y = 2
-( 6x - 2y = 5)
0x + 10y = -3
y = -3/10 ...
try this method for you question...
