solve the system x-2y=0 3x=0

x - 2y = 0

3x      =
0

First, multiply everything in the first equation by
3

By multiplying, your equation should look
like

3x - 6y =
0

3x         = 0  
now subtract 3x with 3x ( which means also subtract 0 with 0 and 6y with
0y )

By subtracting, your equation should look
like

-6y = 0 now divide both
sides by -6

By dividing your equation should look
like

y = 0 which is your
answer for " y "

Now plug in 0 into one of the
equation

3x - 6 ( 0 ) = 0
multiply -6 with 0

By multiplying, your
equation should look like

3x - 0 = 0
divide both sides by 3

By dividing, your
equation should look like

x = 0/3
simplify

x = 0 
which is your answer for " x "

So your
answer is x = 0      ;     y = 0
