Answer 1

4х - 6,84 = 0,4х
4х - 0,4х = 6,84
3,6х = 6,84
х = 6,84 : 3,6
х = 1,9.
Ответ : х = 1,9.
Удачи)))

Answer 2

4x-0,4x=6,84

3,6x=6,84
x=6,84:3,6
x=68,4:36
x=1,9

Answer 3

To solve the equation 4x - 6.84 = 0.4x, follow these steps:

Step 1: Get rid of the decimal by multiplying the entire equation by 10 to clear the decimals.

10 * (4x - 6.84) = 10 * (0.4x)

Step 2: Distribute the multiplication on both sides.

40x - 68.4 = 4x

Step 3: Isolate the variable term (x) on one side of the equation.

40x - 4x = 68.4

Step 4: Combine like terms on the left side.

36x = 68.4

Step 5: Solve for x by dividing both sides by the coefficient of x (36).

x = 68.4 / 36

Step 6: Simplify the result.

x ≈ 1.9

So, the solution to the equation is approximately x = 1.9.
