Question

solve by elimination method 3x-4y=10 , 4x+3y=5​

Answer 1

Answer:

x = 2

y = (-1)

Step-by-step explanation:

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 eqn 1

(3×2) - 4y = 10

6 - 4y = 10

-4y = 4

y = (-1)

so ,

x = 2

y = (-1)
