Question

5,6 - 3(2 - 0,4x) =0,4(4x+1)=???

Answer 1

5,6 - 3(2 - 0,4x) =0,4(4x+1)
5,6-6+1,2x=1,6x+0,4
1,2x-1,6x=-5,6+6+0,4
-0,4x=0,8
x=-2

Answer 2

Let's simplify the equation step by step:

5,6 - 3(2 - 0,4x) = 0,4(4x + 1)

First, let's simplify the expression within the parentheses:

2 - 0,4x = 2 - 0.4x

Distribute the -3 to the terms inside the parentheses:

5,6 - 3(2 - 0,4x) = 5,6 - 6 + 1.2x

Combine like terms:

5,6 - 6 + 1.2x = -0.4 + 1.2x

Now, let's simplify the other side of the equation:

0,4(4x + 1) = 0.4 * (4x + 1)

Distribute the 0.4 to the terms inside the parentheses:

0.4(4x + 1) = 1.6x + 0.4

Now, we have:

-0.4 + 1.2x = 1.6x + 0.4

To solve for x, we'll isolate the x terms on one side and the constant terms on the other side:

1.2x - 1.6x = 0.4 + 0.4

Combine like terms:

-0.4x = 0.8

To solve for x, divide both sides of the equation by -0.4:

x = 0.8 / -0.4

x = -2

Therefore, the solution to the equation 5,6 - 3(2 - 0,4x) = 0,4(4x + 1) is x = -2.
