Question

How many solutions does the equation -3+3a+6=7 have

Answer 1

Answer: The equation has No Solution.

Explanation:

Given the following equation:

`-3a+3a+6=7`

You can simplify it by adding the like terms.

It is important to remember the, by definition, the like terms have the same variable and the same exponent.

In this case, you can identify that the term
`-3a` and the term
`3a` are "like terms", because their variables and their exponents are the same.

So, if you add them, you get:

`-3a+3a=0`

Then:

`0+6=7\\\\6=7\ (FALSE)`

Therefore, since there is no value that satisfies the equation, you can conclude that the equation has No Solution.
