Question

2,47у – 1,32у + 1,3 = 4,221.

Answer 1

Ответ:

2.54

Пошаговое объяснение:

$2.47y-1.32y+1.3=4.221\\1.15y=4.221-1.3\\1.15y=2.921\\y=2.921:1.15\\y=2.54$

Answer 2

To solve the equation 2.47у - 1.32у + 1.3 = 4.221, we'll simplify the equation and isolate the variable у on one side.

Combining like terms: (2.47у - 1.32у) + 1.3 = 4.221

Subtracting the coefficients of у: (2.47 - 1.32)у + 1.3 = 4.221

Simplifying: 1.15у + 1.3 = 4.221

Now, let's isolate у by moving the constant term to the other side of the equation:

1.15у = 4.221 - 1.3

Simplifying: 1.15у = 2.921

Finally, solve for у by dividing both sides of the equation by 1.15:

у = 2.921 / 1.15

Calculating the result: у ≈ 2.54

Therefore, the approximate solution to the equation 2.47у - 1.32у + 1.3 = 4.221 is у ≈ 2.54.
