Step-by-step explanation:

1.5x + 0.1y = 6.2                              3x - 0.4y = 11.2

15x + 1y = 62                                   30x - 4y = 112


15x+1y=62 * 2

30x-4y=112

 

  30x +    2y=     124                      

(-)30x - (-)4y = (-)112

              6y=12                             15x+1y=62

                y=2                               15x+1(2)=62

                                                      15x=60

                                                        x=4
