Question

Solve for x. 12 = x + 3 X=_____

Answer 1

For this case we must find the value of the variable "x" of the following equation:

$12 = x + 3$

So, we follow the steps:

Subtracting 3 from both sides of the equation we have:

$12-3=x+3-3$

Different signs are subtracted and the sign of the major is placed:

$9 = x\\x = 9$

Thus, the value of x is 9.

Answer:

$x = 9$
