A container has 300 liters of water, and a second container has 700 liters of water. The first container begins filling up at a rate of 5 liters per minute at the same time the second starts draining at a rate of 6 liters per minute. Which equation can be used to find the number of minutes, x, that elapse before the two containers have the same amount of water?

After t minutes, the first container holds

300 + 5t

liters of water, while the second container holds

700 - 6t

liters of water. The two containers hold the same amount of water when

300 + 5t = 700 - 6t

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
