Question

1) 7000-(5210-x)=4569 2) 5,2-(6-y)=3,258 3) 80-(x+4,097)=18,36

Answer 1

Ответ:

Пошаговое объяснение:

1)7000-(5210-x)=4569

7000-5210+x=4569

1790+x=4569

x=4569-1790

x=2779

Ответ: 2779 - 2)5,2 - ( 6 - y ) = 3,258 5.2 - 6 + у=3.258 -0.8+у=3.258 у=3.258+0.8 у=4.058 - 3)80-  ( x + 4, 097)= 18,36

x + 4.097 = 80 - 18.36

x + 4.097 = 61.64

x= 61.64 - 4.097

x = 57.543

Answer 2

To solve these equations for x and y, you'll need to isolate the variable on one side of the equation. Here are the steps for each equation:

1. $7000 - (5210 - x) = 4569$

First, simplify the equation inside the parentheses:

$7000 - 5210 + x = 4569$

Now, isolate x by moving the constants to one side of the equation:

$x = 4569 + 5210 - 7000$

$x = 4779$

2. $5.2 - (6 - y) = 3.258$

Simplify the equation inside the parentheses:

$5.2 - 6 + y = 3.258$

Now, isolate y:

$y = 3.258 + 6 - 5.2$

$y = 4.058$

3. $80 - (x + 4.097) = 18.36$

First, simplify the equation inside the parentheses:

$80 - x - 4.097 = 18.36$

Now, isolate x:

$x = 80 - 4.097 - 18.36$

$x = 57.543$

So, the solutions are:

1. $x = 4779$
2. $y = 4.058$
3. $x = 57.543$
