3(0,4у+3)-0,6у=8 помогите пж

Answer 1

Ответ:

Пошаговое объяснение:

1,2у+9-0,6у=8

1,2у-0,6у=8-9

0,6у=-1

У=-1:0,6

У=-1*5/3

У=-5/3=-1 2/3

Answer 2

To solve the equation 3(0.4u + 3) - 0.6u = 8, we can follow these steps:

1. Distribute the 3 to the terms inside the parentheses: 3 * 0.4u + 3 * 3 - 0.6u = 8 1.2u + 9 - 0.6u = 8

2. Combine like terms: (1.2u - 0.6u) + 9 = 8 0.6u + 9 = 8

3. Move the constant term to the other side of the equation: 0.6u = 8 - 9 0.6u = -1

4. Solve for u by dividing both sides of the equation by 0.6: u = -1 / 0.6 u = -1.67

Therefore, the solution to the equation 3(0.4u + 3) - 0.6u = 8 is u = -1.67.
