Question

6x + 9x – 5,8 = 3,8;

Answer 1

Ответ:

6x + 9x – 5,8 = 3,8

(6 + 9) × х - 5,8 = 3,8

15 × х - 5,8 = 3,8

15х - 5,8 = 3,8

15х = 3,8 + 5,8

15х = 9,6

х = 9,6 : 15

х = 0,64

Answer 2

To solve the equation 6x + 9x - 5.8 = 3.8, we can combine like terms:

15x - 5.8 = 3.8

Next, we can isolate the variable x by moving the constant term (-5.8) to the other side of the equation:

15x = 3.8 + 5.8 15x = 9.6

To find the value of x, we divide both sides of the equation by 15:

x = 9.6 / 15 x ≈ 0.64

Therefore, the solution to the equation is x ≈ 0.64.
