Ответ:

(72,2х+5)-12,35=30,81

72,2х+5=30,81+12,35

72,2х+5=43,16

72,2х=43,16-5

72,2х=38,16

х=38,16÷72,2

х=0,528532 или

$\frac{954}{1805}$

Answer 2

To solve the equation (72,2x + 5) - 12.35 = 30.81, follow these steps:

Step 1: Simplify the expression inside the parentheses. 72.2x + 5 - 12.35 = 30.81

Step 2: Combine like terms. 72.2x - 7.35 = 30.81

Step 3: Isolate the variable term (72.2x) by moving the constant term (-7.35) to the other side of the equation. 72.2x = 30.81 + 7.35

Step 4: Add the constants on the right side. 72.2x = 38.16

Step 5: Solve for x by dividing both sides by 72.2. x = 38.16 / 72.2

Step 6: Calculate the result. x ≈ 0.5288 (rounded to four decimal places)

Therefore, the value of x that satisfies the equation is approximately 0.5288.
