Question

1)15,62+x=20 2)9,54-x=7,268 3)x-36,76=19,24 4)x+0,24=8,1

Answer 1

Упс, легко решить:
1) 15,62+x=20
x=20-15,62
x=4,38

2) 9,54-x=7,268
-x=7,268-9,54
-x=-2,272 или x=2,272

3)x-36,76=19,24
x=19,24+36,76
x=56

4) x+0,24=8,1
x=8,1-0,24
x=7,86

Answer 2

1)15.62+x=20
x=20-15.62
x=4.38
2)9.54-x=7.268
x=9.54-7.268
x=2.272
3)x-36.76=19.24
x=19.24+36.76
x=56
4)x+0.24=8.1
x=8.1-0.24
x=7.86

Answer 3

To solve each of these equations for the variable x, you can follow these steps:

1. 15.62 + x = 20

Subtract 15.62 from both sides of the equation:

x = 20 - 15.62 x = 4.38

So, x = 4.38

2. 9.54 - x = 7.268

Add x to both sides of the equation:

9.54 - x + x = 7.268 + x

This simplifies to:

9.54 = 7.268 + x

Now, subtract 7.268 from both sides:

9.54 - 7.268 = 7.268 - 7.268 + x

2.272 = x

So, x = 2.272

3. x - 36.76 = 19.24

Add 36.76 to both sides of the equation:

x - 36.76 + 36.76 = 19.24 + 36.76

This simplifies to:

x = 56.00

So, x = 56.00

4. x + 0.24 = 8.1

Subtract 0.24 from both sides of the equation:

x + 0.24 - 0.24 = 8.1 - 0.24

x = 7.86

So, x = 7.86
