Multiply the bottom equation by 2 and you'll get

4x + 2y = 12
2x - 2y = 6

Then combine the two equations and the y's will cancel out and you'll get

6x = 18

Divide by 6.

x = 3

4x+2y = 12
  x+  y = 3
                       Times the bottom one by -2
4x+2y=12
2x-2y=-6
                      Cancel out the 2y and -2y and add 4x and 2x, 12 and -6 together
6x=6
                      divide by 6 for x
x=1
                      your answer is 1

Doctor better than teacher debate<br>​
Jet001 [13]

Answer:

A doctor sees more different patients each year than a teacher sees different students. The doctor can affect those people in ways that are much more personal and have much more of an immediate impact on their life. Teachers can help enrich the world intellectually, but doctors help keep us in good health.Both doctors and teachers are crucial professions. ... A doctor is one of the most important professions. After all, these specialists have knowledge and skills to diagnose, treat, and control the course of various diseases. Doctors save our lives.A teacher is better because he/she gives you the first advice on what to do and a doctor follows. Teachers are more knowledgeable than doctors. A teacher has knowledge about politicians, nurses and other professions yet doctors only treat patient. a teacher They encourage students to understand the importance of dedicating themselves to passion projects or endeavors. And success builds upon success. The more a student pushes themselves to accomplish their goals, the more they realize what they are capable of doing.
