Question

solve. 3x+6=12
polynomial​

Answer 1

Answer:

Simplifying

3x + -6 = 12

Reorder the terms:

-6 + 3x = 12

Solving

-6 + 3x = 12

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '6' to each side of the equation.

-6 + 6 + 3x = 12 + 6

Combine like terms: -6 + 6 = 0

0 + 3x = 12 + 6

3x = 12 + 6

Combine like terms: 12 + 6 = 18 3x = 18

Divide each side by '3'.

x = 6

Simplifying

x = 6

Answer 2

Answer:

=>> The value of x is 2.

Step-by-step explanation:

Given that:-

$3x+6=12$

To find:- The value of the expression,

To find the value of x, we must apply the transposition method:

As we have,

=> $3x+6=12$

Now subtract both sides by $6$,

=> $3x + 6 - 6 = 12 - 6$

Simplifying it further, we get

=> $3x = 6$

Divide both sides by $3$,

=> $x = 2$

Hence, the required solution is 2.
