Write the phrase "3 times the difference of 5 and y equals 4" as a variable
expression:

y= (4 -5)3

I think

3(5 - y) = 4 OR 4 = 3(5 - 4)

Step-by-step explanation:

Times means multiplication, and difference means subtraction. It wants us to do subtraction before multiplication, so we put it in parenthesis.

2x^2+5x+17
