Answer:
(-5,2)
Step-by-step explanation:
Using elimination:
Multiply x+9y=13 by -2 which would equal -2x-18y=-26
Then you add the two question together
2x+3y=-4 + -2x-18y=-26
Since 2x-2x=0, you can cross them out
3y+(-18y)= -15y
-4+-26 =-30
You are now left with -15y=-30
Then you divide both by -15
Your answer is y=2, now you need to find x by plugging y into one of the equations
x+9(2)=13
x+18=13
Subtract 18 from both sides
x=-5
