Question

solve the pair of liner equations: x+3y=6, 2x-3y=12​

Answer 1

x + 3y = 6 •••••(1)

2x -3y = 12•••••(2) [Elimination method]

_________

3x = 18

x = 6....ans...

put x = 6 in equ-----(1)

we get,

x + 3y = 6

6 +3y = 6

3y = 6-6

y = 0/3

y = 0.....ans..

Answer 2

Step-by-step explanation:

$x + 3y = 6$

$x = 6 - 3y$

$substitute \: x = 6 - 3y \: in \: equatin \: 2$

$2(6 - 3y) - 3y = 12$

$12 - 3y - 6y = 12$

$- 3y = - 6y$

$actually \: these \: pair \: of \: linear \: equations \: are \: incnsistent \: they \: have \: no \: solution$
