Answer 2

To solve these linear equations, you need to isolate the variable "x" on one side of the equation. Here are the solutions for each of the equations:

1. 2x + 17 = 22 + 3x

   Subtract 2x from both sides: 17 = 22 + x

   Subtract 22 from both sides: -5 = x

   So, x = -5

2. 2x + 7 = x + 5.53

   Subtract x from both sides: x + 7 = 5.53

   Subtract 7 from both sides: x = 5.53 - 7 x = -1.47

3. 5 - 3x = 2x - 8

   Add 3x to both sides: 5 = 5x - 8

   Add 8 to both sides: 13 = 5x

   Divide by 5: x = 13 / 5 x = 2.6

4. 9.5x + 2 = 5.7x - 5.6

   Subtract 5.7x from both sides: 9.5x - 5.7x + 2 = -5.6

   Simplify the left side: 3.8x + 2 = -5.6

   Subtract 2 from both sides: 3.8x = -7.6

   Divide by 3.8: x = -7.6 / 3.8 x = -2

5. 1.5x + 8 = 3.1x + 16

   Subtract 1.5x from both sides: 8 = 1.6x + 16

   Subtract 16 from both sides: -8 = 1.6x

   Divide by 1.6: x = -8 / 1.6 x = -5

6. 2.9x + 7.4 = x + 1.7

   Subtract x from both sides: 2.9x - x + 7.4 = 1.7

   Simplify the left side: 1.9x + 7.4 = 1.7

   Subtract 7.4 from both sides: 1.9x = 1.7 - 7.4 1.9x = -5.7

   Divide by 1.9: x = -5.7 / 1.9 x = -3

So, the solutions for the equations are:

1. x = -5
2. x = -1.47
3. x = 2.6
4. x = -2
5. x = -5
6. x = -3
