Question

0,2(3-5х)-0,3(х-1)=-0,7​

Answer 1

Ответ:

0,2•(3х–5)–0,3•(х-1)= -0,7

0,6x-1-0,3x+0,3=-0,7

0,3x-0,7=-0,7

0,3x=0,7-0,7

0,3x=0|:0,3

x=0

Answer 2

To solve the equation 0.2(3-5x) - 0.3(x-1) = -0.7, we can follow these steps:

1. Distribute the terms inside the parentheses: 0.2 * 3 - 0.2 * 5x - 0.3x + 0.3 = -0.7

2. Simplify the equation: 0.6 - 1x + 0.3 - 0.3x = -0.7

3. Combine like terms: -x - 0.3x = -0.7 - 0.6 - 0.3

   Simplifying further, we have: -1.3x = -1.6

4. Divide both sides of the equation by -1.3 to isolate x: x = (-1.6) / (-1.3)

5. Calculating the result: x ≈ 1.23

Therefore, the solution to the equation is approximately x = 1.23.
