Question

5-3(2-0,4x)=0,4(4x+1)

Answer 1

Відповідь:

Покрокове пояснення:

5-3(2-0,4x)=0,4(4x+1)

5-6+1.2х=1.6х+0.4

1.2х-1.6х=0.4+1

-0.4х=1.4

х=-3.5

Answer 2

Відповідь:

х=-3,5

Покрокове пояснення:

5-3(2-0,4x)=0,4(4x+1)

5-6+1,2х=1,6х+0,4

1,2х-1,6х=0,4+1

-0,4х=1,4

х=1,4/-0,4х

х=-3,5

Answer 3

To solve this equation, you can follow these steps:

1. Distribute the 3 inside the parentheses on the left side:

   5 - 3(2 - 0.4x) = 0.4(4x + 1)

   This simplifies to:

   5 - 6 + 1.2x = 0.4(4x + 1)

2. Combine like terms on the left side:

   -1 + 1.2x = 0.4(4x + 1)

3. Distribute 0.4 on the right side:

   -1 + 1.2x = 1.6x + 0.4

4. Move the 1.6x term to the left side by subtracting 1.6x from both sides of the equation:

   -1 - 1.6x + 1.2x = 0.4

5. Combine like terms on the left side:

   -0.4x - 1 = 0.4

6. Add 1 to both sides of the equation to isolate the -0.4x term:

   -0.4x - 1 + 1 = 0.4 + 1

   -0.4x = 1.4

7. Finally, divide both sides by -0.4 to solve for x:

   (-0.4x)/(-0.4) = 1.4/(-0.4)

   x = -3.5

So, the solution to the equation is x = -3.5.
