Answer 1

1. х=-4
2.х=0
3.х= -1/13

Answer 2

5х+20=0

5х=0-20

5х=-20

х=-20:5

х=-4

Ответ:-4

 

х-8х=0

х2-8х=0 
х(х-8)=0 

Ответ:х=0 х=8

 

6х+7х+1=0 

13х=1

х=13

Ответ:13

Answer 3

1) 5x + 20 = 0 To solve the equation 5x + 20 = 0, we can start by isolating the variable x.

Subtract 20 from both sides: 5x = -20

Now, divide both sides by 5 to solve for x: x = -20 / 5 x = -4

So the solution to the equation 5x + 20 = 0 is x = -4.

2) x - 8x = 0 For the equation x - 8x = 0, we can combine like terms and then solve for x.

Combine like terms: -7x = 0

Now, divide both sides by -7 to solve for x: x = 0 / -7 x = 0

So the solution to the equation x - 8x = 0 is x = 0.

3) 6x + 7x + 1 = 0 To solve the equation 6x + 7x + 1 = 0, we can combine like terms and then isolate the variable x.

Combine like terms: 13x + 1 = 0

Subtract 1 from both sides: 13x = -1

Now, divide both sides by 13 to solve for x: x = -1 / 13 x = -1/13

So the solution to the equation 6x + 7x + 1 = 0 is x = -1/13.
