Ответ:
(Choice C) C Infinitely many solutions.
Step-by-step explanation:
First of all, let us learn about solutions of linear equations in one variable.
The linear equations in one variable usually have one solution.
For example:
When we solve this:
One solution is![x = 3](/tpl/images/0711/2392/2d848.png)
But there can be situations when there are
1. No solutions:
For example:
It means that value x is equal to value of x+9 which can never be true.
Truth is the term on Right Hand Side is always 9 greater than the value of Left Hand Side.
Such situations are called Contradictions.
Here, no solution exists.
2. Infinitely many solutions:
For example:
The Right hand Side is just the simplification of the LHS.
And LHS is always equal to RHS no matter what is the value of variable
.
It means there are infinitely many solutions for this equation.
-----------------------------------------------------
Now, let us have a look at the given equation in the question:
Taking LHS:![-4x-7+10x](/tpl/images/0711/2392/8911e.png)
Taking the terms with
on one side:
which is equal to Right Hand Side.
Hence, as we discussed in case 2 above.
For every value of
the equation holds true.
Correct answer is:
(Choice C) C Infinitely many solutions
