Problema Solution

Two factory plants are making TV panels. Yesterday, Plant A produced 2000 fewer panels than Plant B did. Four percent of the panels from Plant A and 3% of the panels from Plant B were defective. How many panels did Plant A produce, if the two plants together produced 970 defective panels?

Two equations will be 

y-x = 4000

0.03x+0.05y= 680

 

Solving we get x= 6000

y=10000

So plant A produces 6000 and plant B produces 10000
