Solve using substitution or elimination. Remember, you must check your work.
Ostrovityanka [42]

Answer:

The answer to your question is: (1/2, -1/3)

Step-by-step explanation:

Elimination

                           10x - 15y = 10    (I)

                             4x + 6y = 0     (II)

Multiply (I) by 2 and (II) by -5

                          20x - 30y = 20

                         -20x - 30y = 0

                                                                Add both equations

                           0   - 60y = 20

                                       y = -20/60

                                      y = - 1/3

Substitute y in (II)

                          4x + 6(-1/3) = 0

                          4x - 2 = 0

                          4x =  2

                            x = 2/4

                           x = 1/2                      

                4(1/2) + 6(-1/3) = 0

                     4/2 - 6/3 = 0

                      2 - 2 = 0

                            0 = 0
