Question

by cross multiplication method find the value of x ,y in 3x-4y=10,4x+3y=5

Answer 1

Step-by-step explanation:

Heya 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)

sho ,

x = 2

y = (-1)

i hope it helped uh !!

thanks
