The complete question is:
Write the mathematical expression for "Twice the difference of y and 3"
It is given that:
Twice the difference of y and 3
The number is y:
The difference between y and 3:
= (y - 3)
Twice the above number:
= 2(y - 3)
The above expression representing a linear expression; If in the linear expression, one variable is present, then the expression is known as the linear expression in one variable.
Thus, the mathematical expression for twice the difference of y and 3 is 2(y - 3); the answer is 2(y - 3).
