Two machines at a factory are selling cans of soup one machine has already filled 180 cans of soup and fills cans at a rate of 15 per minute. The second machine has already filled 210 cans of soup and fill cans at a rate of 12 per minute Write an equation to show when the two machines will have filled the same number of cans of soup was act as variable

Let x be the number of minutes it takes for the two machines to have filled the same number of cans of soup.

The equation would be:
180 + 15x = 210 + 12x

Simplifying this equation, we get:
3x = 30

Therefore, x = 10 minutes.

So, the two machines will have filled the same number of cans of soup after 10 minutes.
