Question

0,5*(4+x) -0,4*(x-3) =2, 5​

Answer 1

Ответ:   -7.

Пошаговое объяснение:

0.5*(4+x) -0.4*(x-3) =2.5​;

2+0.5x-0.4x+1.2=2.5;

0,1x=-0,7;

x=-7.

Answer 2

To solve the given equation $0.5(4+x) - 0.4(x-3) = 2.5,$ you need to simplify the equation and solve for $x$. Let's break it down step by step:

1. Distribute the constants: $2 + 0.5x - 0.4x + 1.2 = 2.5$

2. Combine like terms: $2.5x + 3.2 = 2.5$

3. Isolate the variable $x$: $2.5x = 2.5 - 3.2$ $2.5x = -0.7$

4. Solve for $x$: $x = -0.7 / 2.5$ $x = -0.28$

So, the solution to the equation is $x = -0.28$.
