Simplify to create an equivalent expression. - 3 (2+4k) + 7 (2k-1) - 3 (2+4k) + 7 (2k-1)

-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

2k-13
