Question

321-x=45020,4-x=-13,6122-y=-20050,3-y=72,4

Answer 1

321-х=450
х=321-450
х=-129;

20,4-х=-13,4
х=-13,4-20,4
х=-33,8;

122-у=-200
у=-200-122
у=-322;

50,3-у=72,4
у=72,4-50,3
у=22,1;

Answer 2

x=-129

x=34

y=322

y=-22.1

Answer 3

To solve the equations, we need to find the values of the variables (x and y) that satisfy each equation. Let's solve them one by one:

1. 321 - x = 45020.4

To isolate x, we need to move 321 to the other side of the equation:

x = 45020.4 - 321 x = 44799.4

So, the value of x is 44799.4.

2. -x = -13.6122

To isolate x, we need to divide both sides by -1:

x = -13.6122 / -1 x = 13.6122

So, the value of x is 13.6122.

3. -y = -20050.3

To isolate y, we need to divide both sides by -1:

y = -20050.3 / -1 y = 20050.3

So, the value of y is 20050.3.

4. 3 - y = 72.4

To isolate y, we need to move 3 to the other side of the equation:

-y = 72.4 - 3 -y = 69.4

Now, divide both sides by -1 to get the value of y:

y = 69.4 / -1 y = -69.4

So, the value of y is -69.4.

To summarize:

• x = 44799.4
• y = 20050.3
• x = 13.6122
• y = -69.4
