Correct Question:
John works as a tutor for $12 an hour and as a waiter for $8 an hour. This month, he worked a combined total of 86 hours at his two jobs.
Let be the number of hours John worked as a tutor this month. Write an expression for the combined total dollar amount he earned this month.
Answer:
Total hours = 86
Let t is the hours he spent on tutoring
then (86-t) is hours spent on waiting
Let Y is the total amount in dollars which is required .
Now; 
y = (tutoring hours x 12$) + (waiting hours x 8$)
Y = 12t + 8(86-t)
 
        
             
        
        
        
X=5.
Explanation: 
Take 3x+1=5x-9 and subtract 1 from both sides.
Now you have 3x=5x-10, Subtract 5x from both sides to get -2x= -10
Now divide both sides by -2 and you have x=5 :).

Answer:
2/7
Step-by-step explanation:
This is because the slope is positive so that gets rid of both of the negatives, and the line is not straight but if the line was horizontally straight then your slope would be zero. So I just did process of elimination.
