2.X=-7
3.
4.-17

Answer 3

To solve these equations for x, you can follow these steps:

1. 25x = -100: Divide both sides by 25 to isolate x: 25x / 25 = -100 / 25 x = -4

2. -2x = -14: Divide both sides by -2 to isolate x: (-2x) / (-2) = (-14) / (-2) x = 7

3. -x/3 = -5: Multiply both sides by 3 to isolate x: (-x/3) * 3 = (-5) * 3 -x = -15 Divide both sides by -1 to find x: x = 15

4. 3x = -51: Divide both sides by 3 to isolate x: 3x / 3 = -51 / 3 x = -17

5. 5x + 70 = 40/8: Simplify the right side by dividing 40 by 8: 5x + 70 = 5 Subtract 70 from both sides: 5x + 70 - 70 = 5 - 70 5x = -65 Divide both sides by 5: 5x / 5 = -65 / 5 x = -13

6. -0.6x = -1.2: Divide both sides by -0.6 to isolate x: (-0.6x) / (-0.6) = (-1.2) / (-0.6) x = 2
