Question

Simplify 2m - [n - (m - 2n)]. -3m - n 3m - n -3m - 3n 3m - 3n

Answer 1

3m-3n

Explanation:

We want to simplify the expression;

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

We expand the parenthesis to obtain;

2m - (n - m + 2n)

2m - ( - m + 3n)

Expand further to get;

2m +m -3n

Combine the first two terms;

3m-3n
