Answer:
school bag = rs.450
umbrella = rs.120
Step-by-step explanation:
cost of school bag= x
cost of umbrella= y
6x+4y=3180. ---> (1)
6x+2y=2940. -----> (2)
subracting (2) from (1)
6x+4y=3180
- 6x+2y=2940
——————
2y=240
——————
=> Y=120.
substituting y in (2)
6x+2[120]=2940
=> 6x=2940-240
6x=2700
X= 450.
Hope this helps ☺️
