test book =x and text book =y
2x+3y=250
meenu
books of some maths =x and text book of cass 9 maths =y
6x+4y=500
Step-by-step explanation:
Answer: Situation can be represented algebraically as 2x + 3y = 250
Step-by-step explanation:
Let the cost of class IX Mathematics book be x and cost of class X Mathematics book be y.
Number of class IX books bought by Sangeetha = 2
Amount spent on class IX books = 2x
Number of class X books bought by Sangeetha = 3
Amount spent on class IX books = 3y
Total amount spent by Sangeetha = 2x +3y
2x + 3y = 250
Number of class IX books bought by Meenu = 4
Amount spent on class IX books = 4x
Number of class X books bought by Meenu = 6
Amount spent on class IX books = 6y
Total amount spent by Sangeetha = 4x +6y
4x + 6y = 500
⇒ 2x + 3y = 250
