Question

3x=4y-6 5x-y=7 solve by elimination ​

Answer 1

Answer:

x = 2 and y = 3

Step-by-step explanation:

3x - 4y = -6

5x - y = 7

multiply equation 1 by 4 and solve

Answer 2

Answer:

∴ x=2 and y=3.

Step-by-step explanation:

3x=4y-6

3x+6=4y

4y-3x=6

-3x+4y=6--------------(1)x5

5x-y=7-----------------(2)x(-3)

  -15x+20y=30

- -15x+3y=-21

------------------------  (subtract)

            17y=51

     17y=51

         y=3

substitute value of 'y' in 2,

  5x-3=7

  5x=7+3

  5x=10

   x=10/5

   x=2

∴ x=2 and y=3.
