Answer:

(x, y) solution: (0, -1)

Explanation:

Method to solve: Elimination:

We can solve through eliminating by first multiplying the entire second equation by 2. This will allow us to eliminate the xs since 16x - 16x = 0:

2(-8x - 6y = 6)

-16x - 12y = 12

Solve for y by eliminating the xs through adding the equations:

Now we want to add this equation and 16x - 10y = 10 to eliminate the xs and solve for y:

16x - 10y = 10

+

-16x - 12y = 12

----------------------------------------------------------------------------------------------------------

(16x - 16x) + (-10y - 12y) = (10 + 12)

-22y = 22

y = -1

Thus, y = -1.

Solving for x:

Now we can solve for x by plugging in -1 for y in 16x - 10y = 10:

16x - 10(-1) = 10

16x + 10 = 10

16x = 0

x = 0

Thus, x = 0.

Therefore, the solution to the system as an ordered pair in (x, y) form is (0, -1)
