2X -8X=0 2) X -25=0 3) 0,5 X + 9=0

Let's solve these equations one by one:

1. 2X - 8X = 0 Combine like terms: -6X = 0 Divide by -6 on both sides: X = 0

2. X - 25 = 0 Add 25 to both sides: X = 25

3. 0.5X + 9 = 0 Subtract 9 from both sides: 0.5X = -9 Multiply by 2 to get rid of the decimal: X = -18

Therefore, the solutions to the equations are:

1. X = 0
2. X = 25
3. X = -18
