Answer:
(3,6)
Step-by-step explanation:
2x-3y = -12
x+y=9. Solve for either y or x
-x. -x
y = -x + 9. Substitute this for the y
2x-3(-x+9)= -12
2x +3x-27 = -12. Add like terms
5x -27 = -12
+27. +27. Inverse operations
5x = 15
÷5. ÷5
x = 3
x + y = 9
3 + y = 9. Substitute 3 for x
-3. -3. Inverse operations
y = 6
Well, for starters, this is more of a question for you than it is for me yet here's something to give you an idea.... I think don't let it get personal and leave your life stories at the door. Also, don't ask yourself, "how can this be done or worked out,", ask the people and if they're biased it's hard to tell so just hope that they leave off topic, etc... Ideas and or comments. The best I can give you.
