Answer:
Step-by-step explanation:
To solve this problem, use the fact that you can perform any operation(with a few exceptions) to both sides of an equation, to isolate the variable.
Simply subtract 3 from both sides to get:
-3x - 3 - 3 = 4x + 3 - 3
-3x - 6 = 4x
Then add 3x to both sides to get:
-3x + 3x - 6 = 4x + 3x
-6 = 7x
Then divide both sides by 7 to get:
-6 / 7 = 7x / 7
-6/7 = x

Answer:
3^8 and 6,561
Step-by-step explanation:
1) Calculate, 3 to the power of what is 27?
Make a table of all of 3's powers until 10. i.e. 3^1 = 3, 3^2 = 9 ......
You will find that 3^3 = 27 and 3^5 is 243
3) Use the formula x^m * x^n = x^m+n and substitue our value.
It should look like this: 3^3 * 3^5 = 3^3+5 = 3^8
4) Make a table as described in step 2 and calculate all of 3's powers up to 10. Look at your table and you will find that 3^8 is equal to 6,561
5) The expression written as a power is
3^8 and
the value: 6,561
Enjoy :)
