Answer:

<em>(18 , - 10) </em>

Step-by-step explanation:

5x + 4y = 50 .... <em>(1)</em>

x + 2y = - 2 ... <em>(2)</em>

Solve (2) for "x"

x = - 2y - 2 .... <em>(3)</em>

(3) ----> (1)

5(- 2y - 2) + 4y = 50 ⇔ - 6y - 10 = 50 ⇒ <u><em>y = - 10</em></u> .... <em>(4) </em>

(4) ----> (2)

x + 2(- 10) = - 2 ⇒<u><em> x = 18</em></u>

<em>(18, - 10)</em>
