Question

Yamini and fatima, two student of class ix of a school, together contributed rs. 100 towards the prime minister's relief fund to help the earthquake victims. write a linear equation which satisfies, this data. (you may take their contributions as rs. x and rs y.) draw the graph of the same.

Answer 1

Answer:

Step-by-step explanation:

let the money contributed by  yamini be x

let the money  contributed by fatima be y

x + y = 100

three solutions to draw the graph:

let x = 25

25 + y = 100

y = 100 - 25

y = 75

solution is (25,75)

let  y = 50

x + 50 = 100

x = 100 - 50

x = 50

solution is ( 50,50)

let x= 40

40 + y = 100

y = 100 - 40

y = 60

solution is (40,60)

the three solutions are (25,75),(50,50),(40,60)
