We're not sure what the question means by "root". It may be what's usually
referred to as the "solution" of the equation ... the number that 'm' must be in
order to make the equation a true statement. Here's how to find the 'solution':
2m + 7 = 8 + m
Subtract 7 from each side:
2m = 1 + m
Subtract 'm' from each side:
m = 1
-2m + 7 = m - 2 +7 +2 = m +2m 9 = 3m 3m = 9 m = 9/3 = 3 to test: -2(3) + 7 = (3) - 2 -6 + 7 = 3 - 2 1 = 1
15,000 to the third power that equals pi plus 12 would make it the square root of 7
Gather like terms: 2m - m + 3 + 4 = m + 7.
Here x is equls to 9 and y is equal to 4
The square root of 149 (7 squared plus 10 squared equals 149).
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
-2m + 7 = m - 2 +7 +2 = m +2m 9 = 3m 3m = 9 m = 9/3 = 3 to test: -2(3) + 7 = (3) - 2 -6 + 7 = 3 - 2 1 = 1
If: -6 = 8-2m Then: m = 7
It is a FALSE statement.
15,000 to the third power that equals pi plus 12 would make it the square root of 7
x = 7
Gather like terms: 2m - m + 3 + 4 = m + 7.
10m - 7
Here x is equls to 9 and y is equal to 4
9m - 28 = 2m Therefore, 7m = 28 m = 28/7 m = 4
It equals 24.
