hey friend
here is your answer
===========================
let,
3x-4y = 10 ----------> {1}
4x+3y = 5 ------------> {2}
{1} × 3 = 9x - 12y = 30
{2} ×4 = 16x + 12y = 20 ====================
= 25x = 50
x = 50/25
x = 2
therefore , x = 2
now place x in eq 1
(3×2) - 4y = 10
6 - 4y = 10
-4y = 4
y = (-1)
so ,
x = 2
y = (-1)
i hope it helped uh !! thank
