Answer 2

I see you have a list of equations, and you would like me to help you solve them. I'll go through each equation and provide the solutions step by step.

Set No. 2:

1. x = 203 + x

   To solve this equation, you can start by isolating x on one side:

   x - x = 203

   0 = 203

   There is no solution to this equation because it leads to an inconsistency.

2. 4x + 12 = 3x + 8

   To solve for x, start by isolating x on one side:

   4x - 3x = 8 - 12

   x = -4

3. 3x - 17 = 8x + 18

   To solve for x, start by isolating x on one side:

   3x - 8x = 18 + 17

   -5x = 35

   x = -7

4. 0.8x + 1450.4x - 2.6

   This equation seems to be incomplete. Please provide the full equation.

5. 0.18x - 3.54 = 0.19x - 2.89

   To solve for x, start by isolating x on one side:

   0.18x - 0.19x = -2.89 + 3.54

   -0.01x = 0.65

   x = -0.65 / (-0.01)

   x = 65

6. -2x + 16 = 5x + 30

   To solve for x, start by isolating x on one side:

   -2x - 5x = 30 - 16

   -7x = 14

   x = 14 / (-7)

   x = -2

7. 11x - 7 = -22 + 5x

   To solve for x, start by isolating x on one side:

   11x - 5x = -22 + 7

   6x = -15

   x = -15 / 6

   x = -2.5

8. 2.8 - 3.2x = 4.8 - 5.1x

   To solve for x, start by isolating x on one side:

   -3.2x + 5.1x = 4.8 - 2.8

   1.9x = 2

   x = 2 / 1.9

   x ≈ 1.0526

9. 14 + 5x = 4x + 3x

   To solve for x, combine like terms on the right side:

   14 + 5x = 7x

   Now, isolate x on one side:

   14 = 7x - 5x

   14 = 2x

   x = 14 / 2

   x = 7

Set No. 3:

1. x + 24 = 2(3 + 2x)

   Distribute the 2 on the right side:

   x + 24 = 6 + 4x

   Move 4x to the left side:

   x - 4x = 6 - 24

   -3x = -18

   x = -18 / (-3)

   x = 6

2. 0.2(5x - 2) = 0.3(2x - 1) - 0.9

   Start by distributing the constants:

   1x - 0.4 = 0.6x - 0.3 - 0.9

   Combine like terms:

   1x - 0.4 = 0.6x - 1.2

   Move 0.6x to the left side:

   1x - 0.6x - 0.4 = -1.2

   0.4x - 0.4 = -1.2

   0.4x = -1.2 + 0.4

   0.4x = -0.8

   x = -0.8 / 0.4

   x = -2

3. 4(1 - 0.5x) = -2/3 + 2x

   Distribute the 4 on the left side:

   4 - 2x = -2/3 + 2x

   Move 2x to the right side:

   4 = -2/3 + 2x + 2x

   4 = -2/3 + 4x

   Add 2/3 to both sides:

   4 + 2/3 = 4x

   (12/3) + (2/3) = 4x

   14/3 = 4x

   x = (14/3) / 4

   x = 14/12

   x = 7/6

4. 5(x + 1.2) = 12.5x

   Distribute the 5 on the left side:

   5x + 6 = 12.5x

   Move 5x to the right side:

   6 = 12.5x - 5x

   6 = 7.5x

   x = 6 / 7.5

   x = 4/5

5. 0.7x - 1.82 = 0.8x + 3.46

   To solve for x, start by isolating x on one side:

   0.7x - 0.8x = 3.46 + 1.82

   -0.1x = 5.28

   x = 5.28 / (-0.1)

   x = -52.8

6. 4.72 - 2.5x = 2x + 2.92

   To solve for x, start by isolating x on one side:

   -2.5x - 2x = 2.92 - 4.72

   -4.5x = -1.8

   x = -1.8 / (-4.5)

   x = 0.4
