Final answer:

To solve the given system of equations, use the method of elimination to eliminate one variable. Then, solve for the remaining variable.

Step-by-step explanation:

To solve the given system of equations, we can use the method of elimination. Multiply the first equation by 2 and the second equation by -3 to eliminate the variable 'x'.

3x - 4y = 26 (1)

2x + 8y = -36 (2)

Multiplying equation (1) by 2 and equation (2) by -3:

6x - 8y = 52 (3)

-6x - 24y = 108 (4)

Add equations (3) and (4) to eliminate the variable 'x':

-32y = 160

y = -5

Substitute the value of 'y' into equation (1) to solve for 'x':

3x - 4(-5) = 26

3x + 20 = 26

3x = 6

x = 2

The correct ordered pair is (2, -5).
