Question

solve using elimination.
-10x - 2y = 20
-4x - 2y = 2
(□, □)
submit

Explanation:

Step1: Subtract the two equations

$(-10x - 2y) - (-4x - 2y) = 20 - 2$
$-6x = 18$

Step2: Solve for x

$x = \frac{18}{-6} = -3$

Step3: Substitute x into second equation

$-4(-3) - 2y = 2$
$12 - 2y = 2$

Step4: Solve for y

$-2y = 2 - 12 = -10$
$y = \frac{-10}{-2} = 5$

Answer:

(-3, 5)
