I am going to use elimination method to solve.

 14x - 12y = -2                      First equation multiplied by 2
-15x +12y = -3                      Second equation multiplied by -3
 -x            = -5

x = 5                                    Multiply each side by -1

7x - 6y = -1                           Equation 1

7(5) - 6y = -1                        Substitute the value of x that you found into equation 1

35 - 6y = -1                          Simplify

-6y = -1 - 35                         Subtract 35 from each side

-6y = -36                              Simplify

y = 6                                    Divide each side by -6
