Answer 1

$\huge \colorbox{yellow}{Question}$

$x = y - 3$

$2x + y = 12$

$\huge \colorbox{yellow}{Answer}$

$x = y - 3 \: (equation \: 1)$

$2x + y = 12 \: (equation \: 2)$

Substituting the value of x in

( equation 2)

$2x + y = 12$

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

$2y - 6 + y = 12$

$2y + y = 12 + 6$

$3y = 18$

$y = 18 \div 3$

$y = 6$

Now we get y = 6

Substituting the value of y in

( equation 1 )

$x = y - 3$

$x = 6 - 3$

$x = 3$

Now we get x = 3

$\huge \mathsf\red{Final \: Answer}$

y = 6

x = 3
