Find the solution of the system of equations.
-2x + 9y = -41
−2x -5y =1

y = -3      x = 7

Step-by-step explanation:

-2x + 9y = -41

(-2x -5y =1) -1            Multiply this equation by -1 to cancel the x

-2x + 9y = -41

+ 2x + 5y = -1            Add both equations

14y =  -42                  Divide both sides by 14

y = -3

Plug -3 in for y into one of the equations

-2x + 9(-3) = -41          Multiply 9(-3)

-2x - 27 = -41

     + 27 + 27              Add 27 to both sides

-2x = -14                      Divide both sides by -2

x = 7
