Solve the system of equation
kherson [118]

Answer:

The answer to your question is:

x = -10; y = 8

Step-by-step explanation:

Solve equations by elimination method                          

                                              2x + 3y = 4    (1)

                                               x + 2y = 6    (2)

Multiply 2 by -2

                                              2x + 3y = 4

                                             -2x - 4y = -12

                                                    -y = -8

                                                     y = 8

Substitute y in (2)

                                             x + 2(8) = 6

                                            x = 6 - 16

                                            x = -10
