Question

-0,8(3x-0.6)-0.9=0.2(6x-2.7) Решите пожалуйста

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=12/360
x=1/30

Answer 2

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

Step 1: Distribute the terms on both sides of the equation. -0.8 * 3x + 0.8 * 0.6 - 0.9 = 0.2 * 6x - 0.2 * 2.7

Simplifying this equation gives us: -2.4x + 0.48 - 0.9 = 1.2x - 0.54

Step 2: Combine like terms. -2.4x - 0.42 = 1.2x - 0.54

Step 3: Move all the terms containing x to one side of the equation and the constant terms to the other side. -2.4x - 1.2x = -0.54 + 0.42

Simplifying this equation gives us: -3.6x = -0.12

Step 4: Solve for x by dividing both sides of the equation by -3.6. x = -0.12 / -3.6

Simplifying this equation gives us: x = 0.0333 (rounded to four decimal places)

Therefore, the solution to the equation -0.8(3x - 0.6) - 0.9 = 0.2(6x - 2.7) is x = 0.0333.
