tentukan penyelesaian spldv dengan metode eliminasi. 4x=5y 3y=7-5x tolong jawab

4x = 5y ---> 4x - 5y = 0
3y = 7 - 5x ----> 5x + 3y = 7
(4x-5y=0)×5
(5x+3y=7)×4
20x-25y = 0
20x - 12y = 28
_____________ _
13 y = -28
y = -28/13
(4x-5y=0)×3
(5x + 3y = 7)×5
12x - 15y = 0
25x + 15y = 35
__________ _
-13 x. = -35
x = -35/-13
