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 14 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 teo machines will have filled the same number of cans of soup. use x as your variable.
12x - 210 = 15x - 180
12x + 180 = 15x + 210
12x + 210 = 15x + 180
210 - 12x = 180 - 15x
1 answer
12x + 180 = 15x + 210
