Step-by-step explanation:
Answer:
D) This number is a true solution of the original equation.
Step-by-step explanation:
The solution of an equation is x = -5.
This could be the solution of a linear equation because the linear equation has the highest degrees of 1.
For example, x + 5 = 0
The solution for the above equation is x = -5
-5 + 5 = 0
0 = 0, which is true.
Here is another example.
2x + 10 = 0
Subtracting both sides by 10, we get
2x + 10 - 10 = 0 - 10
2x = -10
Dividing both sides by 2, we get
x = -5
Let's plug in x = -5 and test the result.
2(-5) + 10 = 0
-10 + 10 = 0
0 = 0
Which is true
Therefore, x = -5 is solution of the above equation.
For the above examples, we can conclude that x = -5 can be the true solution of the equations.
Answer is D) This number is a true solution of the original equation.
