Solve the following system of equations and show all of your work.

2x + 5y = −3
−15x − 5y = −10

My answer is
2x + 5y = -3
+-15x - 5y= -10

---------------

-13x = -13

x= 1

2(1) + 5y = -3
2 + 5y -3
5y = -5
y= -1

(x,y) = ( 1, -1)

Is this good?

you know you can check your answers by subbing in what you got for x and y in either of the original equations, and if they come out equal, then it is corrct
