<em>Hey there!</em>

Well to find the solution the the given system,
3y - 2x = -9
y = -2x + 5
So to find x lets plug in -2x + 5 for y in 3y - 2x = -9.
3(-2x + 5) - 2x = -9
Distribute
-6x + 15 - 2x = -9
-8x + 15 = -9
-15 to both sides
-8x = -24
Divide -8 to both sides
<u>x = 3</u>
<u />
Now that we have x which is 3, we can plug in 3 for x in y = -2x + 5.
y = -2(3) + 5
y = -6 + 5
<u>y = -1</u>
<u><em /></u>
So the solution is (3,-1).

Here is you're answer:
In order to find the answer you have to switch all the options into decimals to see which one is equivalent to 2.46!
<-- You're answer.
Therefore you're answer is option C "2 23/50." Remember when wanting to find the decimal divide the numerator by the denominator after you convert the mixed number (if it's a mixed number) into a improper fraction!
Hope this helps!
