Question

0,3(2x-5)+2(0,5x+3)=0,4(4x-7)+7.2

Answer 1

Ответ:

уравнение корней не имеет

Объяснение:

0,3(2x-5)+2(0,5x+3)=0,4(4x-7)+7.2

0,6х - 1,5 + 1х + 6 = 1,6х - 2,8 + 7,2

0,6х + 1х - 1,6х = 1,5 - 6 - 2,8 + 7,2

0 • х = - 0,1

Уравнение корней не имеет, так как не существует чисел, которые при умножении на 0 давали бы в произведении число, отличное от нуля.

Answer 2

To solve the equation 0.3(2x - 5) + 2(0.5x + 3) = 0.4(4x - 7) + 7.2, you can follow these steps:

1. Distribute the numbers inside the parentheses:

0.6x - 1.5 + 1x + 6 = 1.6x - 2.8 + 7.2

2. Combine like terms on both sides of the equation:

(0.6x + 1x) - 1.5 + 6 = 1.6x - 2.8 + 7.2

1.6x - 1.5 + 6 = 1.6x + 4.4

3. Simplify further:

1.6x + 4.5 = 1.6x + 4.4

4. Subtract 1.6x from both sides of the equation to isolate the constant terms:

1.6x - 1.6x + 4.5 = 1.6x - 1.6x + 4.4

4.5 = 4.4

5. Since the equation 4.5 = 4.4 is not true, this means that there is no solution to the original equation. The equation is inconsistent, and there are no values of x that will satisfy it.

In other words, the original equation has no solution.
