How many solutions does this equation have? a + 3 + 2a = -1 + 3a + 4

Students were asked to answer a question at academics and to tell what is most important for them to succeed. One which response stood out from the rest was practice. Successful persons commonly not born successful; they become successful through hard work and persistence. If you would like to accomplish your goals, keep this in mind! the following some question and answer examples that you could implement to boost your knowledge and gain insight that will guide you to continue your school studies.


How many solutions does this equation have?
a + 3 + 2a = -1 + 3a + 4


Answer: There are infinitely many solutions of this equation.

Step-by-step explanation:

The given equation :

First we try to solve the above equation  by combining the like terms (by reordering them), we get

Subtracting 3a from both sides (by using subtracting property of equality), we get

, which is absolutely a correct fact.

That means, the equation has infinitely many solutions as a can take any real value .

Thus , there are infinitely many solutions of this equation.

From the answer and question examples above, hopefully, they might help the student answer the question they had been looking for and notice of each and every thing declared in the answer above. Then would certainly carry out some sharing in a group discussion and also study with the classmate that is related to the topic, so another student also gain some enlightenment and still keeps up the school learning.
