Answer:

22

Step-by-step explanation:

We are given the expression:—

\displaystyle \large{5n-3}

When n = 5, substitute/change n to 5:—

\displaystyle \large{5(5)-3}

Evaluate:—

\displaystyle \large{25-3=\boxed{22}}

__________________________________________________________

<u>Summary</u>

  <u>Substitution</u>

Changing or replacing from a term to another terms/expression is called substitution.

Examples:—

If we are given the expression \displaystyle \large{2y-1} and we want to find the value when y = 4, simply replace y-term to 4.

\displaystyle \large{2(4)-1=8-1=\boxed{7}}
