explain
ya just a wait
And we also know
2x + 9000 = 5x
Now we can solve for x:
2x + 9000 = 5x
9000 = 3x
3000 = x
And since the population of the town is 7x, that means the population is 21,000.
2x + 9000 = 5x
Now we can solve for x:
2x + 9000 = 5x
9000 = 3x
3000 = x
And since the population of the town is 7x, that means the population is 21,000.
