<u>Part 1) </u>The sum of 4 and three times a number is 19
Let
x----------> the number
we know that

therefore
<u>the answer part 1) is equal to</u>
The number is equal to 
<u>Part 2)</u> The difference of twice a number and 7 is 9
Let
x----------> the number
we know that

therefore
<u>the answer part 2) is equal to</u>
The number is equal to 
<u>Part 3) </u>Ten less the quotient of a number and 3 is 6
Let
x----------> the number
we know that

therefore
<u>the answer part 3) is equal to</u>
The number is equal to 
<u>Part 4)</u> Five times the sum of a number and 4 is -15
Let
x----------> the number
we know that

therefore
<u>the answer part 4) is equal to</u>
The number is equal to 
The answer to this is about c
Answer:
I believe Awnser B.. (0.5, 0)
Step-by-step explanation:

Let's check if (3 , 6) is the point of intersection of the given lines ~

and

If the point is the point of intersection of these two lines, then it should satisfy both the equations ~
let's try each of them, using x coordinate of point.



So, the point didn't actually satisfy one of the equation. hence we can infer that the given statement is wrong.
There is one potential solutions and no extraneous solutions.
