Which system of linear equations has the ordered pair (-2,8) as its solution? Oy - 2x = 12 and x - 2y = -18
O x – 2y = 12 and y - 2x = -18
Oy + 2x = 12 and x + 2y = -18
O x + 2y = 12 and y + 2x = -18

The solution to the system of linear equations is:

(x, y) = (-2, 8)

Hence, y - 2x = 12 and x - 2y = -18  has the ordered pair (-2,8) as its solution. Thus, option A is correct.

Step-by-step explanation:

Checking the first system of equations

y - 2x = 12

x - 2y = -18

solving the first system of equations

adding the equations

solving -3x=6 for x

Divide both sides by -3

Simplify

Subtract 8 from both sides

Simplify

Divide both sides by 2

Simplify

Therefore, the solution to the system of linear equations is:

(x, y) = (-2, 8)

Hence, y - 2x = 12 and x - 2y = -18  has the ordered pair (-2,8) as its solution. Thus, option A is correct.
