-3y=18 y=-6 x-(-6)=10 x+6=10 x=10-6 x=4
therefore x=4,y=-6 is answer
can u write the firsrt 1 out like that
@sammy5592 how did u get 3x+y=12 u should get 3x=12 check again.
i multiplied first equation by 2 then subtracted from 2nd equation ..this gives y .put y value in any one of the equations u will get x,theefore x,y u got is solution
no i mean how you did the second equation
did u got @sammy5592
???
did u understand the solution i replied for above problem
yes
