Answer 2

1. (4,5y - 4y) - 8,1 = 2,2 Simplify the left side of the equation first: (0.5y) - 8.1 = 2.2 Then add 8.1 to both sides of the equation: 0.5y = 10.3 Finally, divide both sides of the equation by 0.5: y = 20.6

Therefore, the solution is y = 20.6.

2. 3,5x + 5,1x = 24,94 Combine the like terms on the left side of the equation: 8.6x = 24.94 Then divide both sides of the equation by 8.6: x = 2.9

Therefore, the solution is x = 2.9.

3. (9,5y - 9y) - 1,4 = 10,6 Simplify the left side of the equation first: 0.5y - 1.4 = 10.6 Then add 1.4 to both sides of the equation: 0.5y = 12 Finally, divide both sides of the equation by 0.5: y = 24

Therefore, the solution is y = 24.

4. (12 - x) * 6,5 = 23,4 Divide both sides of the equation by 6.5: 12 - x = 3.6 Then subtract 12 from both sides of the equation: -x = -8.4 Finally, divide both sides of the equation by -1: x = 8.4

Therefore, the solution is x = 8.4.

5. (y - 3,3) : 5,3 = 0,07 Multiply both sides of the equation by 5.3: y - 3.3 = 0.371 Then add 3.3 to both sides of the equation: y = 3.671

Therefore, the solution is y = 3.671.

6. 153 + 0,625y = 215,5 Subtract 153 from both sides of the equation: 0.625y = 62.5 Finally, divide both sides of the equation by 0.625: y = 100

Therefore, the solution is y = 100.

7. 0,32x + 0,47 = 12,8 Subtract 0.47 from both sides of the equation: 0.32x = 12.33 Finally, divide both sides of the equation by 0.32: x = 38.5

Therefore, the solution is x = 38.5.
