Question

6,8*(5,086-1,56x)+3,8=5,5

Answer 1

Объяснение:

6,8*(5,086-1,56х)+3,8=5,5

6,8*(5,086-1,56х)=5,5-3,8

6,8*(5,086-1,56х)=1,7

5,086-1,56х=1,7:6,8

5,086-1,56х=0,25

1,56х=5,086-0,25

1,56х=4,836

х=4,836:1,56

х=3,1

-----------------------------------------

6,8*(5,086-1,56*3,1)+3,8=5,5

5,5=5,5

Ответ:х=3,1

Answer 2

To solve the equation 6.8 * (5.086 - 1.56x) + 3.8 = 5.5, follow these steps:

1. Start by simplifying the equation:

6.8 * (5.086 - 1.56x) + 3.8 = 5.5

2. Distribute 6.8 into the parentheses:

34.6488 - 10.608x + 3.8 = 5.5

3. Combine like terms by adding 3.8 to both sides of the equation:

34.6488 - 10.608x + 3.8 + 3.8 = 5.5 + 3.8

4. Simplify the right side:

34.6488 - 10.608x + 3.8 + 3.8 = 9.3

5. Combine like terms on the left side:

34.6488 + 3.8 - 10.608x + 3.8 = 9.3

6. Combine the constants on the left side:

38.4488 - 10.608x = 9.3

7. Now, isolate the variable term by subtracting 38.4488 from both sides of the equation:

38.4488 - 10.608x - 38.4488 = 9.3 - 38.4488

-10.608x = -29.1488

8. Finally, solve for x by dividing both sides by -10.608:

x = -29.1488 / -10.608 x ≈ 2.7475

So, the solution to the equation is approximately x ≈ 2.7475.
