Answer 1

45-х=38,783

х=45-38,783

х=6,217

 

(х+1,7)-6,02=10,4

х+1,7-6,02=10,4

х=10,4-1,7+6,02

х=14,72

 

х+27,621=38

х=38-27,621

х=10,379

 

(8,3-х)-0,02=3,4

8,3-х-0,02=3,4

8,28-х=3,4

х=4,88 

Answer 2

1. 45 - x = 38.783

To solve for x, we can isolate it by moving the constant term to the other side of the equation:

45 - 38.783 = x

Simplifying the left side:

6.217 = x

So the solution is x = 6.217.

2. (x + 1.7) - 6.02 = 10.4

To solve for x, we can first simplify the equation:

x + 1.7 - 6.02 = 10.4

Next, combine like terms:

x - 4.32 = 10.4

To isolate x, we add 4.32 to both sides of the equation:

x = 10.4 + 4.32

x = 14.72

So the solution is x = 14.72.

3. x + 27.621 = 38.4

To solve for x, we can isolate it by moving the constant term to the other side of the equation:

x = 38.4 - 27.621

Simplifying the right side:

x = 10.779

So the solution is x = 10.779.

4. (8.3 - x) - 0.02 = 3.4

To solve for x, we can first simplify the equation:

8.3 - x - 0.02 = 3.4

Next, combine like terms:

8.28 - x = 3.4

To isolate x, we subtract 8.28 from both sides of the equation:

-x = 3.4 - 8.28

-x = -4.88

To solve for x, we multiply both sides by -1 to change the sign:

x = 4.88

So the solution is x = 4.88.
