Answer 2

Hi dear,

Method #01

x = 2y + 6
x - 2y = 6......(1)

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


Multiply equation (1) with 2

2x - 4y = 12.......(3)
y - 2x = -3.......... from (2)

Solving equation (2) and (3)

-3y = 9
y = -3......(4)

Putting the value of (4) equation in (1)
x = 2(-3) + 6
x = 0



Method #02

x = 2y + 6.......(1)
y = 2x - 3........(2)

y = 2 (2y + 6) - 3
y = 4y + 12 - 3
y-4y = 12 - 3
-3y = 9
y = -3

_______________________

x = 2y + 6
x = 2( - 3) + 6
x = -6 + 6
x = 0

So, Here value of x = 0 and y = -3

Thank you
