Question

Solve the following system of equations: (1 point)

x - 2y = 14
x + 3y = 9
O (1, 12)
O (-1, -12)
O (12, -1)
O (12, 1)

Answer 1

(12,-1)

Explanation:

Plug in the x and y values into the equation to see if it gives you 14 and 9.

Option 1:

(1) - 2(12)

1 - 24 = -23 Not it

Option 2:

(-1)-2(-12)

-1 + 24 = 23 Not it

Option 3:

(12) - 2(-1)

12 +2 = 14 Yes, but make sure with the second equation

12 +3(-1)

12 - 3 . Works

Answer is (12,-1)
