Question

Check if 3 is the root of 2x + 6 =12​

Answer 1

Answer:

• ∴  Yes, $3$ is the root of $2x+6=12$

Step-by-step explanation:

Given : $2x+6=12$

To find : Whether $3$ is the root of given equation or not.

Solution :

• The given equation is $2x+6=12$.

• In order to find whether $3$ is the root of given equation or not, we have to put $x=3$ in the given equation.
• Then, we have to check whether this root satisfies the equation or not that means to check whether left hand side is equal to right hand side or not.
• ∴ Put $x=3$ in given equation, we get

      ∴  $2*3+6=12$

             ∴  $12 = 12$

          ∴  L.H.S. = R.H.S.

• ∴  The value of $x=3$ satisfies the given equation.
• ∴  Yes, $3$ is the root of $2x+6=12$.
