Question

0.2 ×( 5х -2)=-1.2+1.4х

Answer 1

Ответ:

x=2

Пошаговое объяснение:

0.2 ×( 5х -2)=-1.2+1.4х

x-0.4=-1.2+1.4x

x-1.4x=-1.2+0.4

-0.4x=-0.8

x=2

Answer 2

Ответ:

0.2 ×( 5х -2)=-1.2+1.4х

х-0,4=-1,2+1,4х

1,2-0,4=1,4х-х

0,8=0,4х

х=0,8÷0,4

х=2

Answer 3

To solve the equation 0.2 * (5x - 2) = -1.2 + 1.4x, you can follow these steps:

1. Distribute 0.2 on the left side of the equation:

0.2 * 5x - 0.2 * 2 = -1.2 + 1.4x

1x - 0.4 = -1.2 + 1.4x

2. Move the 1.4x term to the left side by subtracting 1.4x from both sides:

1x - 1.4x - 0.4 = -1.2

-0.4x - 0.4 = -1.2

3. Add 0.4 to both sides to isolate the variable:

-0.4x - 0.4 + 0.4 = -1.2 + 0.4

-0.4x = -0.8

4. Finally, divide by -0.4 to solve for x:

x = (-0.8) / (-0.4)

x = 2

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