Answer 1

3х=1200+7800
3х=9000
х=3000

Answer 2

3 * x -7800 = 1200
x= 1200+7800
x=9000 : 3 
x= 3000
ПРОВЕРКА :
3 * 3000 - 7800=1200

Answer 3

To solve for x in the equation 3x - 7800 = 1200, we need to isolate the variable x on one side of the equation.

We can do this by adding 7800 to both sides of the equation:

3x - 7800 + 7800 = 1200 + 7800

Simplifying:

3x = 9000

Finally, we can solve for x by dividing both sides by 3:

3x/3 = 9000/3

Simplifying:

x = 3000

Therefore, the solution is x = 3000.
