Question

0,7(3y-1,5)=3,2(1-2y)​

Answer 1

Ответ:   0.5.

Пошаговое объяснение:

0,7(3y-1,5)=3,2(1-2y)​;

2.1y-1.05=3.2-6.4y;

2.1y+6.4y=3.2+1.05;

8.5y=4.25;

y=4.25:8.5;

y=0.5.

Answer 2

To solve the equation 0.7(3y - 1.5) = 3.2(1 - 2y), we can follow these steps:

1. Distribute the coefficients: 0.7 * 3y - 0.7 * 1.5 = 3.2 * 1 - 3.2 * 2y

2. Simplify both sides: 2.1y - 1.05 = 3.2 - 6.4y

3. Rearrange the terms: 2.1y + 6.4y = 3.2 + 1.05

4. Combine like terms: 8.5y = 4.25

5. Divide both sides by 8.5 to solve for y: y = 4.25 / 8.5

6. Simplify: y = 0.5

Therefore, the solution to the equation 0.7(3y - 1.5) = 3.2(1 - 2y) is y = 0.5.
