We're not sure what the question means by "root". It may be what's usuallyreferred to as the "solution" of the equation ... the number that 'm' must be inorder to make the equation a true statement. Here's how to find the 'solution':2m + 7 = 8 + mSubtract 7 from each side:2m = 1 + mSubtract 'm' from each side:m = 1
It is a FALSE statement.
Gather like terms: 2m - m + 3 + 4 = m + 7.
(m + 5)(m - 1) = 7 m2 + 4m - 5 = 7 m2 + 4m - 12 = 0 (m + 6)(m - 2) m = -6, 2.
It equals 24.
2m+7-m=-402m-m+7=-40m+7=-40m=-47
6m + 7 - 2m + 1 = 4m + 8 If you meant: (6m + 7) - (2m + 1) = 4m + 6

If: -6 = 8-2m Then: m = 7
It is a FALSE statement.
Gather like terms: 2m - m + 3 + 4 = m + 7.
10m - 7
9m - 28 = 2m Therefore, 7m = 28 m = 28/7 m = 4
(m + 5)(m - 1) = 7 m2 + 4m - 5 = 7 m2 + 4m - 12 = 0 (m + 6)(m - 2) m = -6, 2.
5m + 7 - 2m - 1 = 3m + 6
It equals 24.
