Question

8x+y=9 and 3x+5y=15 find the value of x and y by elimination method

Answer 1

Step-by-step explanation:

multiplying in eqn 1 by 5 solve the linear equations u get two values of x and y which is our answer OK friend

Answer 2

Answer:

(8x + y = 9)5 ⇒ 40x + 5y = 45

3x + 5y = 15  ⇒ 3x + 5y = 15

                         (-)    (-)       (-)

                         ---------------------

                          37x = 30

x = 30/37

8x + y = 9 ⇒ 240/37 + y = 9 ⇒ y = 93/37
