Answer :

To solve for [tex]\( f \)[/tex] in the equation

[tex]\[ \frac{f-13}{2} = 3, \][/tex]

we follow these steps:

1. Isolate the expression involving [tex]\( f \)[/tex]:
Begin by eliminating the fraction. Multiply both sides of the equation by 2:

[tex]\[ 2 \cdot \frac{f-13}{2} = 2 \cdot 3. \][/tex]

Simplifying both sides, we get:

[tex]\[ f - 13 = 6. \][/tex]

2. Solve for [tex]\( f \)[/tex]:
To isolate [tex]\( f \)[/tex], add 13 to both sides of the equation:

[tex]\[ f - 13 + 13 = 6 + 13. \][/tex]

This simplifies to:

[tex]\[ f = 19. \][/tex]

Therefore, the value of [tex]\( f \)[/tex] is

[tex]\[ \boxed{19}. \][/tex]
