2 printers can print 7500 lines if 1st printer prints for 2

[Jen123]

Together, two printers can print 7500 lines if the first printer prints for 2 minutes and the second prints for 1 minute. If the first printer prints for 1 minute and the second prints for 2 minutes, they can print 9000 lines together. Find the number of lines per minute that each printer prints.

What i tried:
7500/2=3750
9000-7500=1500
3750-1500=2250 first printer
7500-2250= 5250 second printer

Is this correct??

Is this correct?? - NO

Start by naming variables

assume

the first printer speed = F lines/min

the second printer speed = S lines/min

"Together, two printers can print 7500 lines if the first printer prints for 2 minutes and the second prints for 1 minute

Then

2 * F + S = 7500..................................................................(1)

Now for miulate the second equation from

"If the first printer prints for 1 minute and the second prints for 2 minutes, they can print 9000 lines together"

Now you'll have two equations and two unknowns - solve by your favorite method.
