11y -3x = 8

-3x = -16y + 33

 

Rearrange  these  as

 

-3x + 11y   =  8

-3x + 16y  =  33           subtract te second equation from the first

 

-5y   =  -25         divide   both sides by  -5

y  = 5

 

And   we can find   x  by  using   

 -3x +  11(5) =  8

-3x + 55    = 8          subtract 55 from both sides

-3x  = -47                divide both sides by -3

x = 47/3
