X-2y=4. -3x+5y=-3. solving linear systems using multiplication and addition show your work

Answers

-3x+5y=-3
3x -6y= 12
Multiplied the first equation by 3 so the x's will cancel.
Adding the two equations we get
-y=9
y=-9
Now plug y back in to either equation and solve for x. x-2(-9)=4
x+18=4
x=-14
(-14,-9)
