The equation 3m - 3m - 7 = 0, simplifies to -7 = 0 this means that the the solution is no solution, since -7 doesn't equal 0.
15-b=7.
Not sure what you mean; that equation certainly has a solution.
Another solution for x+y = 7 is y = -x+7
3, 7, 21. 3x7 is the only equation that equals 21, and so these are the only factors of 21.
2x7 = 14 x7 = 7 3x7 = 3*7 = 21

15-b=7.
3(7 + 2) = 3x7 + 3x2 is an example of the distributive law.The distributive law connects multiplication and addition.

x=2/7
Another solution for x+y = 7 is y = -x+7
An equation never equals a number, but its solution often does.-- An equation with a solution of six: [ 3x - 14 = 4 ]-- An equation with a solution of three: [ 14 - 10x = -16 ]-- An equation with both solutions: [ x2 - 9x + 20 = 2 ]An equation that equals 6 is 10 - 4 = 6An equation that equals 3 is 10 - 7 = 3
If you mean 28 = 7+y then the solution of the equation is y = 21
That is an algebraic equation. If you are asking what the solution is for the above equation, it would be:d = 7
