Solve each system using elimination. 3x+3y=27 x-3y=-11

x=4

y=10

Step-by-step explanation:

3x + 3y = 27

x - 3y = - 11 (add these up so 3y will be eliminated and you'll have x only)

4x = 16

now let's eliminate x (you can put 4 instead of x though)

3x + 3y = 27

-3 / x - 3y = - 11 (multiple the the 2nd equation with - 3 to eliminate x)

3x + 3y = 27

-3x + 3y = 33

6y = 60
