Part 1: Decide whether you would use the graphing, substitution, or elimination method to solve the following system of equations. Explain, in complete sentences, why you chose that method.
Part 2: Solve the following system of equations and show all of your work.

   2x + 5y = −3
−15x − 5y = −10

anonymous · Answer

I'd use elimination because all I would need to do in order to isolate a variable is add the two equations.

anonymous · Answer

2x+5y=-3
+ -15x-5y=-10
_____________________
-13x=-13
x=1

2(1)+5y=-3
2+5y=-3
5y=-5
y=-1

So x equals 1 and y equals negative one which can be written as:
(1,-1)
