    Answer:y=6.61,x=-6.46

    Step-by-step explanation:

    3x+7y=-26(×5)

             –

    5x+3y=-14(×3)

    =15x+35y=-130

               –

     15x+9y=-42

    subtracting the 2 equations =15x-15x+35y-9y=-130-(-42)

    =26y=172

    y=172÷26

    y=6.61

    substitute y in the first equation=3x+6.61=-26

    3x=-26+6.61=-19.39

    x=-19.39÷3

    x=-6.46
