Question

1,2-4x-3(2x+0,7)=-2,4

Answer 1

1,2-4x-3(2x+0,7)=-2,4

1,2 - 4x - 6x - 2,1 = -2,4

-10x - 0,9 = -2,4

10x = 2,4 - 0,9

10x = 1,5

x = 1,5 : 10

x = 0,15

Answer 2

To solve this equation, you need to simplify the left-hand side by expanding the brackets and collecting like terms, and then isolate the variable, x.

Here are the steps:

1. Distribute the -3 to the terms inside the parentheses:

1,2 - 4x - 6x - 2,1 = -2,4

2. Combine the like terms on the left-hand side:

-9,9 - 10x = -2,4

3. Add 9,9 to both sides to isolate the variable, x:

-10x = 7,5

4. Divide both sides by -10 to solve for x:

x = -0,75

Therefore, the solution to the equation is x = -0,75.
