Question

Решите мне, пожалуйста. 3,6дробная черта под чертой х-1,2 = 7,8дробная черта под чертой 6,5 Кто решит, тому большое спасибо!!

Answer 1

3,6 / х-1,2 = 7,8 / 6,5
3,6*6,5 = 7,8*(х-1,2)
23,4=7,8х-9,36
7,8х=32,76
х=32,76/7,8
х=4,2

Answer 2

Solving the Equation

To solve the equation 3.6 / (x - 1.2) = 7.8 / 6.5, we can follow these steps:

Step 1: Cross-multiply to eliminate the fractions. Step 2: Simplify the equation. Step 3: Solve for the variable.

Let's go through each step in detail.

Step 1: Cross-Multiply

To eliminate the fractions, we can cross-multiply the numerator of the left side with the denominator of the right side, and vice versa. This gives us:

(3.6) * (6.5) = (7.8) * (x - 1.2)

Simplifying this equation gives us:

23.4 = 7.8x - 9.36

Step 2: Simplify the Equation

Next, we simplify the equation by combining like terms. We add 9.36 to both sides of the equation to isolate the variable term:

23.4 + 9.36 = 7.8x

Simplifying further gives us:

32.76 = 7.8x

Step 3: Solve for the Variable

To solve for x, we divide both sides of the equation by 7.8:

x = 32.76 / 7.8

Evaluating this expression gives us:

x ≈ 4.2

Therefore, the solution to the equation 3.6 / (x - 1.2) = 7.8 / 6.5 is approximately x = 4.2.

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