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
It is a FALSE statement.
Here x is equls to 9 and y is equal to 4
Gather like terms: 2m - m + 3 + 4 = m + 7.
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
15,000 to the third power that equals pi plus 12 would make it the square root of 7
If: -6 = 8-2m Then: m = 7
It is a FALSE statement.
x = 7
Here x is equls to 9 and y is equal to 4
Gather like terms: 2m - m + 3 + 4 = m + 7.
10m - 7
9m - 28 = 2m Therefore, 7m = 28 m = 28/7 m = 4
Using the quadratic equation formula: x = -5-/+ the square root of 7
