Question

-0,8(3x-0,6)-0,9=0,2(6x-2,7)

Answer 1

-0,8(3x-0,6)-0,9=0,2(6x-2,7)

-2.4x + 0.48 - 0.9 = 1.2x - 0.54

-2.4x - 1.2x = -0.54 - 0.48 + 0.9

-3.6x = -0.12

x= -0.12 : (-3.6)

x= 0.033 = 1/30

Ответ: 1/30

Answer 2

To solve the equation -0.8(3x - 0.6) - 0.9 = 0.2(6x - 2.7), follow these steps:

Step 1: Distribute the coefficients on both sides of the equation. Step 2: Combine like terms. Step 3: Isolate the variable term on one side and the constant term on the other side. Step 4: Solve for x.

Let's proceed with the calculations:

Step 1: -0.8(3x) - 0.8(-0.6) - 0.9 = 0.2(6x) - 0.2(2.7)

Step 2: -2.4x + 0.48 - 0.9 = 1.2x - 0.54

Step 3: -2.4x - 0.42 = 1.2x - 0.54

Step 4: Move the x terms to one side and the constant terms to the other side: -2.4x - 1.2x = -0.54 + 0.42

Combine like terms: -3.6x = -0.12

Now, solve for x by dividing both sides by -3.6: x = (-0.12) / (-3.6)

x ≈ 0.0333 (rounded to four decimal places)

Therefore, the solution for the equation is approximately x = 0.0333.
