Question - Expression Evaluation with Substitution
Solution:
To evaluate the expression, simply substitute $$ x = 20 $$ into the expression and simplify:\[ \frac{5(x - 8)}{6} - 1 \]Plugging in $$ x = 20 $$:\[ \frac{5(20 - 8)}{6} - 1 \]\[ \frac{5(12)}{6} - 1 \]\[ \frac{60}{6} - 1 \]\[ 10 - 1 \]\[ 9 \]So, the value of the expression when $$ x = 20 $$ is 9.
