Question

if 12 x + 17 Y is equal to 48 and 17 X + 12 Y is equal to 68 then what is the value of x and y

Answer 1

Hii..

12x+17y=48--------------1
17x+12y=68--------------2

add equation 1 and 2

so the equ become 29x+29y=116====

x+y=4-----------3


subtract equ 1 from 2

so the equ become

5x-5y=20===x-y=4--------4


add equ 3 and 4

so then we get x=4 and y=0
