Step-by-step explanation:

given, 5x+8y=18............(1). [×6]

6x+12y=12...........(2) [×5]

now , solving this by elimination method , we get:

30x + 48y = 108

30x + 60y = 60

– – –

______________

-12y = +48

=> y = -4

from (1), we get

5x + 48×(-4) = 18

= 5x -192-18 =0

= 5x -210

= x = 210/5 = 42.
