Solving for a variable means to rewrite the equation so that the desired variable is alone on one side. So, we have to "move" all the other variables/constants in order to make this happen. We are allowed to add/subtract the same quantity from both sides, or to multiply/divide both sides by any non-zero number.
Let's start with the first example: we are given
11. 
the variable 
is not alone on the right hand side because it is multiplied by 
. We can reverse this by dividing both sides by : the equation becomes
So, we have written the equation as 
, which means that now sits alone on one side of the equation, and thus we have solved the equation for !
Similarly, we do all the others:
12. 
Subtract 
from both sides to get
13. 
Subtract 
from both sides to get
Now divide both sides by 
to get
14. 
Multiply both sides by 2:
Divide both sides by 
:

Answer:
Typist A can type faster
Step-by-step explanation:
Replace the t in w = 50t with any numbers and graph the points you get
You can see that typist A can type 50 words per minute when typist B can only type 40
