Can someone explain the elimination method to me for this problem?

x = -8, y = 4.

Step-by-step explanation:

5x + 3y = -28

5x + 10y = 0

If we subtract these 2 equations we eliminate  x:-

0 + 3y - 10y = -28

-7y = -28

y = -28/-7 = 4.

Now substitute y = 4 in the first equation:

5x + 3(4) = -28

5x + 12 = -28

5x = -40

x = -8.

if this is really you s much. i only have 3 points left and i have 2 questions to ask
