Question

3x – 4y= 16 ; 2x – 3y = 10​

Answer 1

Answer:-

3x - 4y = 16 ••••••••• (i)

2x - 3y = 10 •••••••• (ii)

Multiplying equation (i) by 2 and equation (ii) by 3 we get,

6x - 8y = 32 ••••••• (iii)

6x - 9y = 30 ••••••• (iv)

Subtracting equation (iv) from (iii) we get,

y = -2

Putting the value in equation (i) we get,

3x - 8 = 16

3x = 24

x = 8

Answer 2

Answer:

3x - 4y = 16 -(1)

2x - 3y = 10 -(2)

from (1) and (2)

     6x - 8y = 32

     6x - 9y = 30

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

  y = 2

  x = 8
