Question

3*(4-1,9x)=1,2 - 0,3x

Answer 1

3(4-1,9x)=1,2-0,3x

12-5,7x=1,2-0,3x

-5,4x=-10,8

x=2

Answer 2

Ответ:x=2

Пошаговое объяснение: раскрываем скобки, умножая все на 3 , получаем: 12-5.7х=1.2-0.3х переносим неизвестное в левую часть : -5.7х+0.3х=1.2-12

Приводим подобные: -5.4х=1,2-12

-5,4х= -10,8

x=2

Answer 3

It looks like you have an equation that needs to be solved for the variable "x". Let's solve it step by step:

Given equation: 3*(4 - 1.9x) = 1.2 - 0.3x

Step 1: Distribute the 3 on the left side of the equation: 12 - 3 * 1.9x = 1.2 - 0.3x

Step 2: Simplify both sides: 12 - 5.7x = 1.2 - 0.3x

Step 3: Move the terms with "x" to one side of the equation: -5.7x + 0.3x = 1.2 - 12

Step 4: Combine the "x" terms and constants on both sides: -5.4x = -10.8

Step 5: Divide by the coefficient of "x" to solve for "x": x = -10.8 / -5.4 x = 2

So, the solution to the equation is x = 2.
