Question

0, 2(x-5)=0, 3 (5-x)-4, 5

Answer 1

Ответ:

0,2(x-5)=0,3(5-x)-4,5

0.2х-1=1.5-0.3х-4.5

0.2х+0.3х=1.5-4.5+1

0.5х=-2

х=-4

Answer 2

Ответ:

-4

Пошаговое объяснение:

0,2х-1=1,5-0,3х-4,5

0,2х+0,3х=-4,5+1,5+1

0,5х=-2

х=-4

Answer 3

To solve the equations, let's work through them one by one:

1. 0: The equation 0 = 0 is already satisfied. It means that the solution is any real number. In other words, the equation is true for all values of x.

2. 2(x-5) = 0: To solve this equation, we'll distribute the 2 to the terms inside the parentheses: 2x - 10 = 0 Next, we'll add 10 to both sides to isolate the x term: 2x = 10 Finally, we'll divide both sides by 2 to solve for x: x = 5

3. 3(5-x) - 4 = 5: First, we'll simplify the equation: 15 - 3x - 4 = 5 Combine like terms: 11 - 3x = 5 Next, we'll subtract 11 from both sides: -3x = 5 - 11 -3x = -6 To solve for x, we'll divide both sides by -3: x = -6 / -3 x = 2

Therefore, the solutions to the given equations are: x = 5 and x = 2.
