Answer : x= 1 3/7
First, simplify 1 × (x + 2) to (x + 2) / Your problem should look like:
Second, expand. / Your problem should look like:
Third, add x to both sides. / Your problem should look like:
Fourth, simplify 6x - 12 + x to get 7x - 12. / Your problem should look like:
Fifth, add 12 to both sides. / Your problem should look like:
Sixth, add -2 + 12 to get 10. / Your problem should look like:
Seventh, divide both sides by 7. / Your problem should look like:
Eighth, switch your sides. / Your problem should look like:

l is given... l = 16
And V is given... V = 144
so...
144 = 16 * w * h
next
divide by 16 on both sides to find the value the w*h equals
then find the possible values of w and h

We can compare this using example:
Suppose the two fractions are and
When we simplify before multiplying:
(dividing both numerator and denominator by 5) in simplified form becomes
Similarly becomes
Now multiplying:
=
When we simplify after multiplying:
=
Now simplifying this:
Dividing both numerator and denominator by 10; we get
Now dividing by 2:
Now dividing by 3:
-----------------------------------------------------------------------------------------------
Now, we can see and compare that when we multiply after simplifying, the result is simplified and calculation is easier.
When we do not simplify and multiply at first, the results are bigger numbers and it is difficult to simplify bigger numbers.
a denominator gets simplified, we will cross it out with a slash and write the new
numerator or denominator next to it (either above it or below it).The number you divide by (the 4) does not get indicated in any way! You only
think about it in your mind: “I divide 12 by 4, and get 3. I divide 20 by 4, and get 5.”You may not see any advantage over the “old” method yet, but this shortcut will
come in handy soon.

different types of coins there are. All we know is that all 10 of them
on the scale at the same time have 45 grams of mass.
IF all the coins happen to be identical ... AND each one is worn down
the same amount, AND each one has the same amount of dirt and oil
on it ... then each one has (45/10) = 4.5 grams of mass.
But those are some big IFs.
There are 4.5 grams in each coin.
