Asked by Angie

A company has two printers. Printer A prints a pages per minute, and Printer B prints b pages per minute. When Printer A prints for 3 minutes and Printer B prints 5 minutes, a total of 70 pages are printed. When Printer A prints for 6 minutes and Printer B prints for 9 minutes, a total of 135 pages are printed. This situation is represented by this system of equations.
3a + 5b = 70
6a + 9b = 135
How many pages per minute does Printer A print?
F. 5
G. 11
H. 15
I. 30
Answered by Henry
Multiply Eq1 by -9, and multiply Eq2 by 5:

-27a - 45b = 630
+30a + 45b = 675
3a = 45
a = 15.
