Question

0,4(7-2×) =4,6-0,6(×-6) решите уравнение ​

Answer 1

Ответ:0.6х-1.2+4.6=2.8+0.4х

0.6х-0.4х=2.8+1.2-4.6

0.2х=-0.6

х=-3

Ответ: -3.

0,6х-1,2+4,6=2,8+0,4х

0,2х=-0,6

х=-3

Answer 2

To solve the equation, let's first simplify the expressions on both sides and then isolate the variable "×."

Given equation: 0.4(7 - 2×) = 4.6 - 0.6(× - 6)

Step 1: Distribute the values inside the parentheses: 0.4 * 7 - 0.4 * 2× = 4.6 - 0.6× + 0.6 * 6

Step 2: Simplify the expressions: 2.8 - 0.8× = 4.6 - 0.6× + 3.6

Step 3: Combine like terms by moving the variable terms to one side and constants to the other side of the equation: -0.8× + 0.6× = 4.6 + 3.6 - 2.8

Step 4: Simplify further: -0.2× = 5.4

Step 5: Isolate the variable "×" by dividing both sides by -0.2: × = 5.4 / (-0.2)

Step 6: Calculate the value of "×": × = -27

Therefore, the solution to the equation is × = -27.
