Solve by elimination:
x + 9y = 8
-6X - 9y = -3

(-1,1)

Step-by-step explanation:

x + 9y = 8

-6x - 9y = -3

Add the two equations together to eliminate y

x + 9y = 8

-6x - 9y = -3

-5x   = 5

Divide by -5

-5x/-5 = 5/-5

x = -1

Now solve for y by substituting into the first equation

x+9y = 8

-1 + 9y =8

Add 1 to each side

-1+1 + 9y = 8+1

9y=9

Divide each side by 9

9y/9 = 9/9

y = 1
