Ответ:х=1/2

Answer 2

To solve the equation $6(2.5-1.5x)=20.5-2.5(3+2x)$, we can follow these steps:

First, let's distribute the terms: $6(2.5) - 6(1.5x) = 20.5 - 2.5(3) - 2.5(2x).$

Simplify the terms: $15 - 9x = 20.5 - 7.5 - 5x.$

Simplify further: $15 - 9x = 13 - 5x.$

Now, let's isolate the variable $x$ by moving all terms involving $x$ to one side of the equation: $15 - 13 = 9x - 5x.$

Simplify the equation further: $2 = 4x.$

Now, solve for $x$: $x = \frac{2}{4} = \frac{1}{2}.$

Therefore, the solution for the equation is $x = \frac{1}{2}$.
