Answer:
let the cost of oranges = X
let the cost of apples = y
5 oranges = 5x
3 apples = 3y
cost of 5 oranges and 3 apples = 30 Rs
= 5x + 3y = 30 (1st equation)
2 oranges = 2x
4 apples = 4y
cost of 2 oranges and 4 apples = 26 Rs.
2x + 4y = 26 (2nd equation)
subtract 2nd equation from 1st equation
5x + 3y = 30
2x + 4y = 26
4( 5x + 3y = 30)
3( 2x + 4y = 26)
20x + 12y = 120
6x + 12y = 78
20x + 12y = 120
-6x - 12y = -78
14x = 42
X = 42/ 14
X = 3
put the value of X in 2nd equation
2x + 4y = 26
2( 3) + 4y = 26
6 + 4y = 26
4y = 26 - 6
4y = 20
y = 20 / 4
y = 5
