<h3>What is an expression?</h3>
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
y (0.5 + 6)
Expanding we get,
y x 0.5 + 6y
0.5y + 6y
Thus,
The expanded form of the expression y (0.5 + 6) is
0.5y + 6y
