Answer 2

4) х*9=810
х=810:9
х=90
5) 47х=0
х=0:47
х=0
6) 99х=99
х=99:99
х=1
7) 84:х=6
6х=84
х=84:6
х=14
8) х:76=12
х=12*76
х=912
9) х:71=0
х=0*71
х=0
10) х:29=11
х=11*29
х=319

Answer 3

Let's solve each equation one by one:

4. х ∙ 9 = 810

To find the value of х, we need to divide both sides of the equation by 9:

(х ∙ 9) / 9 = 810 / 9

х = 90

So, the solution to this equation is х = 90.

5. 47х = 0

To solve for х, we divide both sides of the equation by 47:

47х / 47 = 0 / 47

х = 0

The solution to this equation is х = 0.

6. 99х = 99

Dividing both sides of the equation by 99, we get:

(99х) / 99 = 99 / 99

х = 1

The solution to this equation is х = 1.

7. 84 : х = 6

To solve for х, we can multiply both sides of the equation by х:

(84 / х) ∙ х = 6 ∙ х

84 = 6х

Now, divide both sides of the equation by 6:

84 / 6 = (6х) / 6

14 = х

The solution to this equation is х = 14.

8. х : 76 = 12

To find the value of х, we can multiply both sides of the equation by 76:

(х / 76) ∙ 76 = 12 ∙ 76

х = 912

The solution to this equation is х = 912.

9. х : 71 = 0

Since any number divided by 71 cannot be equal to 0, there is no solution to this equation.

10. х : 29 = 11

Multiplying both sides of the equation by 29, we get:

(х / 29) ∙ 29 = 11 ∙ 29

х = 319

The solution to this equation is х = 319.

So, the solutions to the equations are: 4) х = 90

5. х = 0
6. х = 1
7. х = 14
8. х = 912
9. No solution
10. х = 319
