Question

9. 4x – 3y = 8,
6x=y=24​

Answer 1

Answer:

Step-by-step explanation:

4x - 3y = 8 ..... (1)

6x - y = 24 .....(2)

Multiplying (2) by 3,

3 (6x - y = 24 )

∴ 12x - 3y = 72 ..... (3)

Now, subtracting eq (3) from (1)

    12x - 3y = 72

-    4x - 3y = 8

   (-)   (+)    (-)

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

    8x       = 64

   ∴  x       = 8

Substituting x = 8 in eq (1)

  4x - 3y = 8

∴ 4(8) - 3y = 8

∴ 32 - 3y = 8

  ∴  -3y = 8 - 32

   ∴ -3y = -24

    ∴  y = -24÷-3

    ∴ y = 8
