Question

what is the value of the expression below when $x = 7$ and $y = 3$?
$5x - 3y$

Explanation:

Step1: Substitute x and y values

Substitute \( x = 7 \) and \( y = 3 \) into the expression \( 5x - 3y \).
\( 5\times7 - 3\times3 \)

Step2: Calculate each term

Calculate \( 5\times7 = 35 \) and \( 3\times3 = 9 \).
\( 35 - 9 \)

Step3: Subtract the results

Subtract 9 from 35.
\( 26 \)

Answer:

26
