Question

0.4*(3x-0.8)+6.14=25.02

Answer 1

1,2х-0,32+6,14=25,02
1,2х=25,02+0,32-6,14
1,2х=19,2
х=16

Answer 2

To solve the equation 0.4(3x - 0.8) + 6.14 = 25.02 for x, follow these steps:

1. First, distribute 0.4 into the expression inside the parentheses: 1.2x - 0.32 + 6.14 = 25.02

2. Next, combine like terms by adding 0.32 to both sides of the equation to isolate the x term: 1.2x + 6.14 = 25.02 + 0.32

3. Now, simplify the right side of the equation: 1.2x + 6.14 = 25.34

4. To solve for x, subtract 6.14 from both sides of the equation to isolate the 1.2x term: 1.2x = 25.34 - 6.14

5. Simplify the right side of the equation: 1.2x = 19.20

6. Finally, divide both sides by 1.2 to solve for x: x = 19.20 / 1.2

7. Calculate the value of x: x = 16.00

So, the solution to the equation is x = 16.00.
