Ответ:

4

Пошаговое объяснение:

1) 15х=60

2)х=60:15

3)х=4

Answer 3

To find the value of x in the equation 3x + 5x + 7x = 60, we need to combine like terms on the left side of the equation:

3x + 5x + 7x = 60

Combining the x terms, we get:

15x = 60

Now, to find the value of x, we need to isolate it on one side of the equation. Since 15x means 15 multiplied by x, we can solve for x by dividing both sides of the equation by 15:

15x/15 = 60/15

x = 4

So, the value of x that satisfies the equation is x = 4.
