Question

X + 3 = 9 . Solve for x.

Answer 1

x = 6

Explanation:

x + 3 = 9

=> x = 9 - 3

=> x = 6

Answer 2

`\boxed{ \Huge{\bf \: x = 6}}`

Explanation:

Given equation:-

`x + 3 = 9`

We need to Find the value of x of this equation.

Solution:-

`\sf \longmapsto \: x + 3 = 9`

Subtract 3 from both sides :

`\sf \longmapsto{x } + 3 - 3 = 9 - 3`

Simplify LHS :

`\sf \longmapsto \: x + 0 = 9 - 3`

`\sf \longmapsto \: x = 9 - 3`

Simplify RHS:

`\sf \longmapsto \: x = 9 - 3`

`\sf \longmapsto \: x = 6`

Hence,

`\boxed{\rm x = 6}`

Key Words:-

LHS = Left hand side [ of the equation ]

RHS = Right hand side [ of the equation ]
