Question

(01.02) Choose the best definition for the following term: substitution A letter that holds the place for some unknown value in mathematics A process where you must look for terms that have identical variable parts and then combine their coefficients A process where if two things are equal, one can be put in the place of the other and nothing will change Terms that have identical variable parts

Answer 1

A process where if two things are equal, one can be put in the place of the other and nothing will change

Step-by-step explanation:

In mathematics, the substitution method is a process where if two things or expressions are equal (for example, a letter and the value of the number), one can be put in the place of the other and nothing will change.

Take a look at the following equation:

X + 7 = 10

3 + 7 = 10

In this case, we can substitute the letter X by the number 3 and nothing will change because they both have the same value (X is equal to 3).
