Answer:

x=12,y=3

Step-by-step explanation:

3x-10y = 6            *2  ---------->6x-20y=12

2x + 7y = 45         *3  ---------->6x+21y=135

                                            (-) ----------------

                                                -41y=-123

                                                     y=3

apply y in equation 1

3x-30=6

3x=36

x=12
