Four times a number plus three times a second number is negative nine. Twice the first number plus the second number is three. Call the first number m and the second number n.

m=9

n=-15

Step-by-step explanation:

If you set it up in a systems of equations way, ou would have

    4m+3n=-9

+ . 2m+n=3

You would need to cancel out a variable and in my opinion, canceling m out is easier.

  4m+3n=-9

+-4m-2n=-6

0m+n=-15

n=-15

you then plug this into one of the equations, (in my opinion the 2nd one is easier)

2m-15=3

2m=18

m=9

this gives you m so you can get the answer

m=9 and n=-15
