Answer 2

Ответ:

1) х= -0,8

2) х= -0,2

Пошаговое объяснение:

1)

-(3,2-х)= -4

-3,2+х= -4

х= -4 + 3,2

х= -0,8

2)

6,8-х=7

-х=7-6,8

-х=0,2

х= - 0,2

Answer 3

It looks like you've provided two equations with variables. Let's solve them one by one:

1. $(3 - 2x) = -4$

First, let's isolate the variable $x$:

Subtract 3 from both sides:

$-2x = -4 - 3$

Simplify:

$-2x = -7$

Now, divide both sides by -2 to solve for $x$:

$x = \frac{-7}{-2}$

$x = \frac{7}{2}$

So, the solution for the first equation is $x = \frac{7}{2}$.

2. $6.8 - x = 7$

Subtract 6.8 from both sides:

$-x = 7 - 6.8$

Simplify:

$-x = 0.2$

Multiply both sides by -1 to solve for $x$:

$x = -0.2$

The solution for the second equation is $x = -0.2$.

Therefore, the solutions are:

1. $x = \frac{7}{2}$
2. $x = -0.2$
