Question

29-x=18, x+3=79, 12:x=3, x•9=90 решить уравнения

Answer 1

Ответ:

Пошаговое объяснение:

29-х=18              х*9=90

х=29-18              х=90:9

х=11                      х=10

х+3=79

х=79-3

х=76

12:х=3

х=12:3

х=4

Answer 2

To solve the equations, let's find the value of 'x' in each case:

1. 29 - x = 18 First, isolate 'x' by moving the constant term to the other side: 29 - x - 29 = 18 - 29 -x = -11

Now, divide both sides by -1 to solve for 'x': x = 11

2. x + 3 = 79 Subtract 3 from both sides to isolate 'x': x + 3 - 3 = 79 - 3 x = 76

3. 12 : x = 3 Here, '12 : x' means 12 divided by 'x'. To find 'x', we'll inverse the operation by multiplying both sides by 'x': 12 = 3 * x

Now, divide both sides by 3 to solve for 'x': x = 12 / 3 x = 4

4. x • 9 = 90 Here, 'x • 9' means 'x' multiplied by 9. To find 'x', we'll divide both sides by 9: x • 9 / 9 = 90 / 9 x = 10

So, the solutions to the equations are:

1. x = 11
2. x = 76
3. x = 4
4. x = 10
