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

To evaluate the expression \( 5y - x \) with the given values \( y = 4 \) and \( x = 7 \), we simply substitute these values into the expression: \[ 5(4) - 7 = 20 - 7 = 13 \] So, the evaluated expression results in \( 13 \).
