Answer 2

To solve the equation, follow these steps:

1. Distribute the terms on both sides of the equation.
2. Combine like terms.
3. Isolate the variable on one side of the equation.
4. Solve for the variable.

Let's solve the equation step by step:

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

Step 1: Distribute the terms:

2,5 * 3x - 2,5 * 2 - 4 * 2x - 4 * 0,5 = -4

Step 2: Simplify the equation by performing the multiplication:

7,5x - 5 - 8x - 2 = -4

Step 3: Combine like terms:

(7,5x - 8x) - (5 + 2) = -4

-0,5x - 7 = -4

Step 4: Isolate the variable term:

To isolate x, add 7 to both sides of the equation:

-0,5x = -4 + 7

-0,5x = 3

Step 5: Solve for x:

Divide both sides by -0.5:

x = 3 / -0.5

x = -6

So the solution to the equation is x = -6.
