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 / 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
