Question

6*(3 +5х)=20 - (12х+ 4) срочно 30 балов! полное решение

Answer 1

Ответ:

-1/21

Пошаговое объяснение:

6(3 + 5х) = 20 - (12х + 4)

18 + 30х = 20 - 12х - 4

30х + 12х = 20 - 4 - 18

42х = -2

х = -2 : 42

х = -2/42 или -1/21.

Answer 2

Ответ: x=-2/42
Решение:
6(3+5х)=20-(12х+4)
18+30x=20-12x-4
30x+12x=20-4-18
42x=-2
x=-2/42

Answer 3

6*(3+5x) = 20 - (12x+4)

First, let's distribute the 6 on the left side of the equation: 18 + 30x = 20 - (12x+4)

Next, let's distribute the negative sign on the right side of the equation: 18 + 30x = 20 - 12x - 4

Combine like terms on the right side of the equation: 18 + 30x = 16 - 12x

Now, let's move all the terms involving x to one side of the equation: 30x + 12x = 16 - 18 42x = -2

Finally, solve for x by dividing both sides by 42: x = -2/42 x = -1/21

So the value of x is -1/21.
