Answer 2

Answer:

=> x = $4$ is the root of the equation.

Step-by-step explanation:

As per the given question, we have to verify that given value for x is the root of the equation or not.

Given that:-

$3x-5=7$

where x = $4$

Now, put the value of x as 4 in the given equation,

=> $3 ( 4 ) - 5 = 7$

=> $12 - 5 = 7$

=> $7 = 7$

Hence, $4$ is the root of the equation.
