Regardless of what 'x' is, if you subtract the amount you have
from the amount you have, you end up with zero.
5x-5x
zero
5x-7 is an algebraic expression
8x
5x² - 18x + 9 = (5x² - 15x) - (3x - 9) = 5x(x - 3) - 3(x - 3) = (5x - 3)(x - 3).
X= 2!
If you mean: 5x/7 -6 = x then x = -21
10x - 5x + 5x = 10x
5x - 2x = 3x
3xz
2x squared minus 5x minus 3 factored is (2x+1)(x-3).
5x - 4x = x
which of the following is a factor of x2 - 5x - 6
5x(x - 2)
5x-7 is an algebraic expression
5x
2x squared - 5x - 3 = (2x +1)(x -3)
3x - 5x + x = -x
The equation x2 - 5x - 24 = 0 has the two solutions 8 and -3 for x.
