Question

0,2(x-3)=0,4(7-x)-4,6​

Answer 1

Ответ:

x=-2

Пошаговое объяснение:

0,2(x-3)=0,4(7-x)-4,6

0.2x-0.6=-1,8-0,4x

0,2x+0,4x=-1,8+0,6

0,6x=-1,2

x=-2

Answer 2

Ответ:

0,2(X-3)=0,4(7-X)-4,6

0,2X-0,6=2,8-0,4X-4,6

0,2X-0,6+1,8+0,4X=0

0,6X+1,2=0

0,6X=-1,2

X=-2

Answer 3

To solve the given equation $0.2(x-3) = 0.4(7-x) - 4.6$, we'll follow these steps:

1. Distribute the constants and simplify the equation.
2. Combine like terms.
3. Solve for $x$.

Let's start by distributing and simplifying:

$0.2x - 0.6 = 2.8 - 0.4x - 4.6$

Now, let's combine like terms:

$0.2x - 0.6 = -0.4x - 1.8$

Next, let's isolate $x$ on one side of the equation. First, let's add $0.4x$ to both sides and add $0.6$ to both sides:

$0.2x + 0.4x = -1.8 + 0.6$

Now, combine the $x$ terms:

$0.6x = -1.2$

Finally, divide both sides by $0.6$ to solve for $x$:

$x = \frac{-1.2}{0.6}$

$x = -2$

So, the solution for the equation is $x = -2$.
