Question

На сколько корень уравнения 1.2*(0.5-5x)+4.2=3*(4-2.1x) больше -10? Решите пожалуйста

Answer 1

0,6-6х+4,2=12-6,3х 
-6х+6,3х=12-4,8 
0,3х= 7,2
х=7,2:0,3 
х=24

Answer 2

Solving the Equation for the Value of x

To solve the equation 1.2*(0.5-5x)+4.2=3*(4-2.1x) for the value of x, we'll follow these steps:

1. Distribute the terms inside the parentheses. 2. Combine like terms. 3. Solve for x.

Let's proceed with the solution.

Step 1: Distribute the Terms

The given equation is: 1.2*(0.5-5x)+4.2=3*(4-2.1x)

Distributing the terms inside the parentheses, we get: 1.2*0.5 - 1.2*5x + 4.2 = 3*4 - 3*2.1x

Simplifying, we have: 0.6 - 6x + 4.2 = 12 - 6.3x

Step 2: Combine Like Terms

Combining like terms, we get: 4.8 - 6x = 12 - 6.3x

Step 3: Solve for x

To solve for x, we'll first get all the x terms on one side of the equation.

Adding 6.3x to both sides, we get: 4.8 + 0.3x = 12

Subtracting 4.8 from both sides, we get: 0.3x = 7.2

Finally, solving for x, we have: x = 7.2 / 0.3 x = 24

Conclusion

The value of x that satisfies the given equation is x = 24.
