Answer:

the answer is x=-9

Step-by-step explanation:

The value of a solution of the rational equation that must discard and nullify the context of the equation is -9

Word problems in mathematics require crucial understanding because they are used to solve a real-life scenario. It entails the gathering of all information necessary to arrive at the solution.

From the information given:

  • It will take Charlene and Gina 18 minutes to organize comic books
  • Gina will use = 15 minutes if Gina works alone

where x represents the number of minutes

The equation representing the above information is given as:

[tex]\mathbf{\mathbf{\dfrac{1}{x}+ \dfrac{1}{x+15}= \dfrac{1}{18}}}[/tex]

The objective of this question is to determine the value in which it will discard and nullify the context of the above equation.

In that case, the number must be a number in which when substituted into the above equation will result in having the same value on the left-hand side and the right-hand side.

From the given option, the number that results in that is -9

[tex]\mathbf{\mathbf{\dfrac{1}{-9}+ \dfrac{1}{-9+15}= \dfrac{1}{18}}}[/tex]

[tex]\mathbf{\mathbf{0.05555555556= 0.05555555556}}[/tex]
