Answer 2

Ответ:

3

Пошаговое объяснение:

10х= 42-12

10х=30

х=30/10

х=3

Answer 3

To solve the equation, let's first combine like terms:

x + 9x + 12 = 42

Combine the x terms:

10x + 12 = 42

Next, isolate the variable x by subtracting 12 from both sides of the equation:

10x = 42 - 12 10x = 30

Finally, divide both sides by 10 to solve for x:

x = 30 / 10 x = 3

So, the solution to the equation is x = 3.
