Two machines at a factory are filling 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 fills 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. Use x as your variable.

1.12x+210=15x+180

2.100-3x=150-5x
3.180-20x=140-16x ; x= 10
4. 92+16x=104+13x ; x = -4
5.120-7x=150-9x ; x=15
100%

The equation to represent when the two machines will have filled the same number of cans of soup can be written as:

180 + 15x = 210 + 12x
