Since   x   = y

 

Then

 

-3x  - x =  4

 

-4x   = 4

 

x  = 4  /  -4     =  -1

 

So   y  = the same thing   

 

 

cool cool cool

ok since we know that x=y we only need to solve for x and then y would be the same thing

 

so we basically just solve the equation -3x-y=4 (divide both sides by -4 to get x=-1) and y would be the same thing as x.
