(-9, -9)

Step-by-step explanation:

3x + 5y = −72 and 2x + 3y = –45 is equivalent to:

3x + 5y = −72

2x + 3y = –45

Let's eliminate x.  To do this, multiply the first equation by -2 and the second equation by +3.  We get:

-6x - 10y = 144

6x +  9y = -135

     -y = 9

So y = -9.  Substituting -9 for y in the first equation, we get

3x + 5(-9) = -72, or

3x - 45 = -72.  Then 3x = -27, and x = -9.

The solution to this system is (-9, -9).

i hope that helps ?? if not let me know please
