Answer 2

Ответ:

$0.2(7-2x)=2.3-0.3(3x-5) \\ 1.4 - 0.4x = 2.3 - 0.9x + 1.5 \\ 1.4 - 0.4x = 3.8 - 0.9x \\ - 0.4x + 0.9x = 3.8 - 1.4 \\ 0.5x = 2.4 \\ x = 4.8$

Answer 3

To solve the equation 0.2(7 - 2x) = 2.3 - 0.3(3x - 5), you'll need to simplify and isolate the variable x. Here are the steps:

1. Distribute the constants on both sides of the equation:

0.2 * 7 - 0.2 * 2x = 2.3 - 0.3 * 3x + 0.3 * 5

2. Now, simplify each side of the equation:

1.4 - 0.4x = 2.3 - 0.9x + 1.5

3. Group like terms:

-0.4x + 0.9x = 2.3 + 1.4 - 1.5

4. Combine the x terms:

0.5x = 2.2

5. Finally, solve for x by dividing both sides by 0.5:

x = 2.2 / 0.5

x = 4.4

So, the solution to the equation is x = 4.4.
