Substitute $$ x=7,y=4 $$ into the expression $$ 5y-x $$.
Evaluate the expression by following steps:
- step0: Evaluate:
  $$5y-x$$
- step1: Substitute:
  $$5	imes 4-7$$
- step2: Multiply the numbers:
  $$20-7$$
- step3: Subtract the numbers:
  $$13$$
When $$ y=4 $$ and $$ x=7 $$, the expression $$ 5y-x $$ evaluates to 13.
When $$ y=4 $$ and $$ x=7 $$, the expression $$ 5y-x $$ equals 13.

Evaluate the expression when \( y=4 \) and \( x=7 \). \[ 5 y-x \]
