3. решите уравнение: 12 + 8,3х + 1,5х = 95,3. 20 баллов . Помогите плизз

Answer 1

12 + 8,3х + 1,5х = 95,3
9,8х=95,3-12
9,8х=83,3
х=83,3:9,8
х=8,5

Answer 2

8,3х+1,5х=95,3-12
9,8х=83.3
Х=83,3:9,8
Х=8,5

Answer 3

Solving the Equation: 12 + 8.3x + 1.5x = 95.3

To solve the equation 12 + 8.3x + 1.5x = 95.3, we need to combine like terms and isolate the variable x.

Combining like terms, we have:

12 + 8.3x + 1.5x = 95.3

To simplify the equation, we can add the coefficients of x:

12 + (8.3 + 1.5)x = 95.3

Simplifying further:

12 + 9.8x = 95.3

Now, we can isolate the variable x by subtracting 12 from both sides of the equation:

12 + 9.8x - 12 = 95.3 - 12

This simplifies to:

9.8x = 83.3

To solve for x, we divide both sides of the equation by 9.8:

(9.8x) / 9.8 = 83.3 / 9.8

This gives us:

x = 8.5

Therefore, the solution to the equation 12 + 8.3x + 1.5x = 95.3 is x = 8.5.

I hope this helps! Let me know if you have any further questions.
