A variable is a letter, for example x, y or z, that represents an unspecified number.
6 + x = 12
To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12.
Hey there!
The answer to your question is 
Given:
First, we distribute the negative sign to both terms (
) This would make the negative and the positive, so we have:
Add them together and we get:

Answer:
Fraction Form: 
Decimal Form: 0.4583
Step-by-step explanation:
Apply the fraction rule: 
Least Common Multiple (LCM) of 12 and 8: 24
Apply the fraction rule:
I believe you can do x + 2.7 = 16.
I took geometry last year and those arrow things are basically saying the line is the same if they have the same number of arrows. Using that logic, you can equal them out and find X.
Your answer is 16 - 2.7
(13.3)
