Answer:
x = 7.3
Step-by-step explanation:
-2x + x-4 = 18
First, Combine Like Terms
-3x + (-4) = 18
Then, do Inverse Operations
-3x + -4 = 18
+ 4 +4
Cancel out the -4 +4 because it will equal zero and won't matter to the equation
-3x = 22
Do Inverse Operations again. In this case, you will divide.
-3x = 22
-3x/-3 = 22/-3
Cancel out the -3x/-3
22/-3 = x
7.3 = x
Log9 =2
3
because logz =y when x^y = z
x
Answer:
7.07
Step-by-step explanation:
M = 4
n = 1
If you substitute in your values, you can see that 4 + 1 = 5
And 4 - 1 = 3
Hope this helped :)
True. If you're just changing the form, yes. But remember when you change one side of an equation, you must change the other in the same way.
