Answer:
Since you are to calculate the value of x, the first thing to do is to collect the like terms, i.e bring all the families of x together.
which implies : x -12x +7x = 7 + 4
-4x = 11
Divide both sides by -4
therefore : x =
Step-by-step explanation:
Answer:

Step-by-step explanation:
Given expression is
To find the completed factor for the given expression:
:
Taking the common number "2" outside to the above expression we get
Now rewritting the above expression as below
(since 16 can be written as the number 2 to the power of 4)
The above expression is of the form
Here and
Therefore it becomes
