Elimination

6x-6y=0
-6x-3y=27

x=-3 and y=-3

Step-by-step explanation:

add the two equations, so 6x-6x, -6y-3y, and 0+27 to get -9y=27. y ends up equaling -3. plug negative 3 into the either of the equations and solve for x, which ends up being -3

7=(n+5)×3

6=P×9

8=(2×B)+8

9=seven multiplied by n

10=eleven plus c

11=x subtract thirty six

12= y divided by 9

13=m plus 20

14=q divided by 12

15=six b plus eight

16=five k minus 3
