Answer:
By elimination method,
2x + 5y = 25
2x - 3y = 1 (-)
----------------
0x + 8y = 24
8y = 24
y = 24/8 = 3
2x - 3y = 1
Substitute value of y
2x -3(3)=1
2x = 1+9= 10
x = 10/2 =5

Answer:
x = 5 and y = 3
Step-by-step explanation:
2x + 5y = 25 ---------------(1)
2x - 3y = 1 ------------------(2)
by eliminetion method
(1) - (2)
2x + 5y = 25
-
2x - 3y = 1.
___-___+___-_______
0 + 8y = 24
y = 24 / 8
y = 3
putting the value of y in (1)
2x + 5y = 25
2x + 5 * 3 = 25
2x + 15 = 25
2x = 25 - 15
2x = 10
x = 10/2
x = 5
