Answer:
x = 2 y = 0
Explanation:
25x + 5y = 50 -------- 1 equ
x + y = 5 ------------- 2 equ
multiply equ 1 in 1 and equ 2 in 5.
25x + 5y = 50 -------- 1 equ × 1
x + y = 5 ------------- 2 equ × 5
25x + 5y = 50 --- equ 3
5x + 5y = 10 ------- equ 4
substract equ 3 in equ 4.
25x + 5y = 50
5x + 5y = 10
- - -
20x + 0 = 40
x = 40/20
x = 2
put this x value for equation 1.
25x + 5y = 50
25(2) + 5y = 50
50 + 5y = 50
5y = 50 - 50
y = 0/5
y = 0
