    Answer:

    The values are

    m = 13

    b = 17

    Step-by-step explanation:

    1239 = 94m + b ——eqn 1

    810 = 61m + b ———–eqn 2

    Let’s take eqn 1, let’s make b the subject of the formula

    1239 – 94m = b

    Since b = 1239 – 94m

    Insert the value of b into the eqn 2

    810 = 61m + (1239 – 94m)

    810 = 61m + 1239 – 94m

    Collect like terms

    810 = 61m – 94m + 1239

    810 = – 33m + 1239

    810 – 1239 = – 33m

    – 429 = – 33m

    The minus sign cancels each other

    Making m the subject

    m = 429 / 33

    m = 13

    Since we’ve gotten the value for m, insert the value of m= 13 into the eqn 1

    1239 = 94m + b

    m = 13

    1239 = 94 (13) + b

    1239 = 1222 + b

    1239 – 1222 = b

    17 = b

    b = 17

    m = 13

    b = 17
