If 2x + 5= -25 and -3m-6=48 what is the product of x and m

1.) 2x + 5= -25 
Subtract 5 from both sides
2x= -30
Divide 2 on both sides so that the only thing remaining on the left side is the variable x.
Final x= -15

2.) -3m-6=48
Add 6 to both sides
-3m= 54
Divide -3 on both sides so that the only thing remaining on the left side is the variable m.
Final m= -18
