Question

x + 2y = 1, 2x - 3y = 12,
Find Dx, Dy​

Answer 1

Answer:

x=27/7, y=-10/7

Step-by-step explanation:

let x+2y=1--------------(1)

2x-3y=12-----------(2)

now from equation (1)

x=1-2y--------(3)

now putting the value of x in equation (2),we get

2(1-2y)-3y=12

2-4y-3y=12

2-7y=12

-7y=12-2

y= -10/7

putting the value of y in (3), we get

x=1-2(-10/7)

=1-(-20/7)

=1+20/7

=7+20/7

x=27/7
