First of all, the first power of 'x' is the highest power in the whole equation,
so we only expect one solution.
You said that <span><u>3x+9 = 21+7x </u>
Subtract 3x from each side:
9 = 21 + 4x
Subtract 21 from each side:
-12 = 4x
Divide each side by 4 :
<u>-3 = x </u>

Answer:
wanna help, but please specify what the (2) means.
our take a picture of the problem and makes me post.
Answer:
She type <u>75 words</u> in 1 minute.
Step-by-step explanation:
Given:
Lolo typed 1,125 words in 15 minutes.
Let w represent the number of words typed each minute.
Now, to find the number of words she type in 1 minute if Lolo typed the same number of words each minute.
So, we solve it by using cross multiplication method:
<u><em>As 1125 words is equivalent to 15 minutes.</em></u>
<u><em>Thus, w number of words equivalent to 1 minutes</em></u>.

By cross multiplying we get:
⇒ 
<em>Dividing both sides by 15 we get:</em>
⇒ 
⇒
Therefore, she type 75 words in 1 minute.
<h3><u>Answer :- </u></h3>
168 km ...
<h3><u>Explanation :- </u></h3>
It is given that the car travels 14km in 25 minutes..
Now , assume that the distance the car travel in 5 hours be x..
- Since 1 hour = 60 minutes..
- 5 hours = 300 minutes ..
• Thus , The two given statements are :-
- 14km -----------------> 25 minutes..
- And, x km -------------> 300 minutes..
<h3><u>We know that , </u></h3>
- The distance travelled by car and the time taken by the car is directly proportional to each other....
<h3>So , </h3>


• Hence , Car can travel 168km in 5 hours ..
Hope this helps you :)
