Solve by the elimination method.
6x+9y=57
-6x+y=33

6x+9y=57
-6x+y=33

  (+)

6x+(-6x)+9y+y=57+33

10y=90   /:10

y=9

-6x+y=33

-6x+9=33  /-9

-6x=24   /:(-6)

x=-4

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
