Question

1. x + 4,06 = - 7,4 2. x - 10,03 = - 2,7 3. 5,09 + x = 1,1 4. - 2x + 8,6 = - 2,04

Answer 1

Пошаговое объяснение:

1. x+4,06 = -7,4

x= -7,4 - 4,06

x= -11,46 ;

2. x-10,03= -2,7

x= -2,7+10,03

x=7,33 ;

3.5,09+x=1,1

x=1,1-5,09

x= -3,99 ;

4.-2x+8,6= -2,04

-2x= -2,04 - 8,6

-2x= -10,64

x=5,32.

Answer 2

Ответ:

Пошаговое объяснение:

1) х+4,06= -7,4

  х=-7,4-4,06

  х= - 11,46___

  2) х-10,03= -2,7

   х=10,03 -2,7

    х=7,33___

 3) 5,09 + х=1,1

    х= -5,09 +1,1

     х = -3,99____

  4)-2х + 8,6 = -2,04

      -2х = -2,04 - 8,6

      -2х = -10,64

       х= 5,32_____

Answer 3

To solve the equations, we'll isolate $x$ on one side of the equation. Here are the steps for each equation:

1. $x + 4.06 = -7.4$

   Subtract 4.06 from both sides:

   $x = -7.4 - 4.06$

   $x = -11.46$

2. $x - 10.03 = -2.7$

   Add 10.03 to both sides:

   $x = -2.7 + 10.03$

   $x = 7.33$

3. $5.09 + x = 1.1$

   Subtract 5.09 from both sides:

   $x = 1.1 - 5.09$

   $x = -3.99$

4. $-2x + 8.6 = -2.04$

   Add 2.04 to both sides:

   $-2x = -2.04 - 8.6$

   $-2x = -10.64$

   Divide both sides by $-2$:

   $x = 5.32$

So, the solutions for the equations are:

1. $x = -11.46$
2. $x = 7.33$
3. $x = -3.99$
4. $x = 5.32$
