If: 3y-7 = 2y+9
Then: 3y-2y = 9+7
So: y = 16
2m + 6
3*(n - 5) = 2*n + 11
2z+9
As an algebraic expression it is: 2x+4
twice as much
A trice, often used to refer to a "trice" in informal language, is not a standard unit of measurement. If you're referring to a "trice" as a moment or a brief period, it typically means a very short time, similar to an instant or a blink of an eye. However, if you intended to ask about something else, please clarify for a more accurate answer.
8+2n
2m + 6
3*(n - 5) = 2*n + 11
Qx2+4
8 more than twice a number d
You write it as5nNothing more, nothing less.

2n+12=x
3>2x
As an algebraic expression it is: 2x+4
2x+3=11
