25x - 4 x - 5x - 5 = 0
Simplify the left side of the equation:
(25 - 4 - 5)x - 5 = 0
16x - 5 = 0
Add 5 to both sides:
16x = 5
Divide by 16:
x = 5/16

3x - 9 x 3 - x = 8
Simplify the left side of the equation:
3x - 9x - 3x = 8
-9x = 8
Divide by -9:
x = -8/9

4x + 3 = -2x
Add 2x to both sides:
6x + 3 = 0
Subtract 3 from both sides:
6x = -3
Divide by 6:
x = -1/2

Therefore, the solutions to the given equations are:
x = 5/16, x = -8/9, x = -1/2
