Question

2.1x - 3(2.5x+3.6) = 10.4x - 7.64

Answer 1

Ответ:

2,1x-3(2,5x+3,6)=10,4x-7,64

2,1x-7,5x-10,8=10,4x-7,64

2,1x-7,5x-10,4x=-7,64+10,8

-15,8x=3,16

x=3,16:(-15,8)

x=-0,2

Answer 3

To solve the given equation for $x$, let's follow these steps:

1. Distribute the terms inside the parentheses.
2. Combine like terms on each side of the equation.
3. Move all $x$-related terms to one side and constants to the other.
4. Simplify and solve for $x$.

Let's proceed with these steps:

$2.1x - 3(2.5x+3.6) = 10.4x - 7.64$

Step 1: Distribute the terms inside the parentheses: $2.1x - 7.5x - 10.8 = 10.4x - 7.64$

Step 2: Combine like terms on each side: $(-5.4x) - 10.8 = 10.4x - 7.64$

Step 3: Move all $x$-related terms to one side and constants to the other: $-5.4x - 10.8 - 10.4x + 7.64 = 0$ $-15.2x - 3.16 = 0$

Step 4: Simplify and solve for $x$: $-15.2x = 3.16$

Now, let's solve for $x$: $x = \frac{3.16}{-15.2} \approx -0.20789473684$
