Question

1) 6400:х=80 2) 1560-х=560 3) х+2087=5125 4) х:9=187

Answer 1

1) 6400:х=80
х=6400:80
х=80.

2)1560 - х=560
х=1560-560
х=1000.

3)х+2087=5125
х=5125-2087
х=3038.

4)х:9=187
х=187*9
х=1683.

Answer 2

To solve the given equations:

1. 6400: x = 80

To solve this equation, you can multiply both sides by x to isolate it on one side:

6400 = 80x

Next, divide both sides by 80:

x = 6400 / 80

Simplifying the right side:

x = 80

Therefore, x = 80.

2. 1560 - x = 560

To solve this equation, you can isolate x by moving the constant term to the other side:

1560 - 560 = x

Simplifying the left side:

1000 = x

Therefore, x = 1000.

3. x + 2087 = 5125

To solve this equation, you can isolate x by moving the constant term to the other side:

x = 5125 - 2087

Simplifying the right side:

x = 3038

Therefore, x = 3038.

4. x:9 = 187

To solve this equation, you can multiply both sides by 9 to isolate x:

9 * (x/9) = 187 * 9

Simplifying:

x = 1683

Therefore, x = 1683.

The solutions to the given equations are:

1. x = 80
2. x = 1000
3. x = 3038
4. x = 1683
