Объяснение:

20+5x=0

5x=-20

x=-4

Answer 2

10*2+5х=0

20+5х=0

5х=0-20

5х=-20

х=-20:5

х=-4

Answer 3

To solve the equation 10x^2 + 5x = 0, we can factor out the common factor of x:

x(10x + 5) = 0

Now, we have two factors: x = 0 and 10x + 5 = 0.

For x = 0, we have one solution.

For 10x + 5 = 0, we can solve for x:

10x = -5 x = -5/10 x = -1/2

Therefore, the solutions to the equation 10x^2 + 5x = 0 are x = 0 and x = -1/2.
