Answer 2

It looks like you have an algebraic expression that you'd like to evaluate for a specific value of x. Let's break down the expression step by step and then substitute the value of x:

Given expression: -4*(2,3x-3) + 2*(5-2,6x) * 3*(0,6x-2)

Step 1: Distribute the constants outside the parentheses: -4 * 2 + 4 * (3x) - 4 * 3 + 2 * 5 - 2 * (2,6x) + 3 * 0 - 3 * 2

Step 2: Simplify the terms: -8 + 12x - 12 + 10 - 5.2x + 0 - 6

Step 3: Combine the like terms: (12x - 5.2x) + (-8 - 12 + 10 - 6)

Simplify further: 6.8x - 16

Now, you want to evaluate this expression for x = 2: Expression = 6.8 * 2 - 16 Expression = 13.6 - 16 Expression = -2.4

So, when x = 2, the value of the expression is -2.4.
