Question

3x - 1,4 + 3x = 4,9​

Answer 1

Ответ:

Пошаговое объяснение:

3x - 1,4 + 3x = 4,9​

6x - 1,4 = 4,9

6x = 4,9 + 1,4

6x = 6,3

x = 6,3 : 6

x = 1,05

Answer 2

3x - 1,4 + 3x = 4,9

3x + 3x = 4,9 + 1,4

6x = 6,3

x = 6,3 : 6

x = 1,05

Answer 3

To solve the equation 3x - 1.4 + 3x = 4.9, we can combine like terms and isolate the variable x.

Combining the x terms on the left side: 3x + 3x - 1.4 = 4.9

Adding the x terms: 6x - 1.4 = 4.9

To isolate the x term, we'll move the constant term (1.4) to the right side by adding 1.4 to both sides: 6x = 4.9 + 1.4 6x = 6.3

Next, we'll solve for x by dividing both sides of the equation by 6: x = 6.3 / 6 x ≈ 1.05

Therefore, the solution to the equation 3x - 1.4 + 3x = 4.9 is approximately x = 1.05.
