Question

Simplify 2m - [n - (m - 2n)].

1 Answer

  • Let's simplify step-by-step.

    2m(n−(m−2n))

    Distribute the Negative Sign:

    =2m+−1(n−(m−2n))

    =2m+−1n+−1(−m)+−1(2n)

    =2m+−n+m+2n

    Combine Like Terms:

    =2m+−n+m+2n

    =(2m+m)+(−n+2n)

    =3m+3n

    Answer:

    =3m3n
