Answer:
a = 1.
Step-by-step explanation:
i guess you want to solve for a:
16 + (22a + a) = 16 + (a + 22)
16 + 23a = 38 + a
22a = 38 - 16 = 22.
a = 1.
What am i solving exactly?
Answer: 3
Step-by-step explanation: The number in front of your variable is called your coefficient so we say that 3 is the coeficient.
Make sure to understand that a variable
is just a letter that represents any number.
Distribute -3 to get rid of the parentheses.
Add 15 to both sides.
Now divide -3 on both sides.
You have your answer!
-3(n+5)=12
<u />-3n-15=12
+15 +15
<u>-3n</u>=<u>27
</u>-3 -3
n=-9 <u /><u>
</u><u />
