    -26 + 4k

    Step-by-step explanation:

    -3 (2+4k) + 7 (2k-1) - 3 (2+4k) + 7 (2k-1)

    Notice that we have 2k-1 as a factor 2 times and 2+4k as a factor 2 times

    -3 (2+4k) - 3 (2+4k) + 7 (2k-1) + 7 (2k-1)

    Think of the factor as a variable 2k-1 = M and 2+4k = P

    -3 (P) - 3 (P) + 7 (M) + 7 (M)

    Combine like terms

    -6P + 14M

    Now substitute back M = 2k-1 and P = 2+4k

    -6 (2+4k) + 14 (2k-1)

    Distribute

    -12 - 24k + 28k - 14

    Combine like terms

    -26 + 4k
