Question

0,5(0,2x-4)-1,7=4,3 ????????????

Answer 1

$\displaystyle 0,5(0,2x-4)-1,7=4,3\\0,1x-2-1,7=4,3\\0,1x-3,7=4,3\\0,1x=4,3+3,7\\0,1x=8\\x=80$

Answer 2

Ответ:

Пошаговое объяснение:0,1х-2-1,7=4,3

0,1х=4,3+2+1,7

0,1х=8

х=8/0,1

х=80

Answer 3

To solve the equation 0.5(0.2x - 4) - 1.7 = 4.3, follow these steps:

1. Distribute the 0.5 on the left side of the equation: 0.5 * 0.2x - 0.5 * 4 - 1.7 = 4.3

2. Simplify the equation: 0.1x - 2 - 1.7 = 4.3

3. Combine like terms on the left side of the equation: 0.1x - 2 - 1.7 = 4.3 0.1x - 3.7 = 4.3

4. Add 3.7 to both sides of the equation to isolate the term with x on the left side: 0.1x - 3.7 + 3.7 = 4.3 + 3.7

5. Simplify: 0.1x = 8.0

6. Finally, divide both sides by 0.1 to solve for x: (0.1x) / 0.1 = 8.0 / 0.1

7. Simplify: x = 80

So, the solution to the equation is x = 80.
