The solution is x = -6 and y = -4.

To solve the system of equations 8x - 8y = -16 and -2x + 6y = -12, we can use the method of combination.

In order to eliminate one variable, let's multiply the first equation by 3 and the second equation by 4.

This will give us 24x - 24y = -48 and -8x + 24y = -48.

Now, add the two equations together to eliminate the variable 'y'.

The resulting equation is 16x = -96.

Divide both sides by 16 to solve for 'x', giving us x = -6.

Now that we have the value of 'x', substitute it back into one of the original equations.

Let's use the first equation: 8x - 8y = -16. Substitute the value of 'x' to get 8(-6) - 8y = -16.

Simplify to get -48 - 8y = -16. Add 48 to both sides to isolate the variable 'y', giving us -8y = 32.

Divide both sides by -8 to solve for 'y', giving us y = -4.

Therefore, the solution to the system of equations is x = -6 and y = -4.

The probable question may be:

Solve the system of equations 8x - 8y = -16 and -2x+6y= -12 by combining the equations.

(8x -8y =-16) (-2x+6y=-12)

8x -8y = -16 -2x+6y=-12
