    6s+4d=$53

    4s+6d=$47

    Multiply 6 in the first equation which is

    36s+24d=$318

    Multiply - 4 in the second equation which is

    -16s-24d=$-188

    Then ...

    36s+24d=$318

    -16s-24d=$-188

    You cancel out the - 24d and + 24d

    36s=$318

    -16s=$-188

    Do the math ...

    20s=$130

    Divide 20 by both sides and answer ...

    s=$6.5
