Question

Simplify : `2{m-3(n+overline(m-2n))}`

Answer 1

`2{m-3(n+overline(m-2n))}`

The overline indicates grouping. Simplify `\overline{m - 2n}`​:

`\overline(m−2n)​=m−2n`

Substitute this back into the expression

2{m − 3(n + (m − 2n))}

Simplify n + (m − 2n)

n + m − 2n = m − n

2{m − 3(m − n)}

Distribute −3 across (m−n):

−3(m − n) = −3m + 3n

2{m + (−3m + 3n)}

m − 3m + 3n = −2m + 3n

Distribute 2 across −2m + 3n

2(−2m + 3n) = −4m + 6n

−4m + 6n
