Question

2x + 3y = 4 4x - 5y = 4 what is the value of x and y​

Answer 1

Answer:

Let kx−3y=4 ..(1)

and 4x−5y=7 ..(2)

Multiplying equation (1) by 5 and equation (2) by 3, we have

5kx−15y=20 ..(3)

12x−15y=21 ..(4)

Since the coefficient of y is same in equations (3) and (4), and the terms on right hand side of equality are different, the coefficients of x cannot be the same.

∴5k

=12

∴k

=

5

12
