Zero. The sum of anything and it's opposite is zero, that's how an opposite is defined.
In this case, the opposite of 2x + 1 is -(2x + 1) = -2x - 1 by the distributive property. Adding like terms, 2x + -2x + 1 +-1 = 0 + 0 = 0.

What is the average of 3x plus 1 and x-3?
Average = (sum of the items) / (number of items)Sum of the items = (3x + 1) + (x - 3) = 4x - 2Number of items = 2Average = (2x - 1)
What is 4x plus 1 equals 2x plus 12 equals?
x=5.54x+1= 2x+12-1 -14x=2x+11-2x -2x2x=11/2 /2x=5.5
Y equals 2x plus 1?
Y = 2x + 1
2x plus x plus opposite x plus -1 equals 7 plus 2 opposite x?
This is an unclear equation, actually some sort of addition. (Opposite means negative? Inverse?) 2x + x + (-x) + (-1) = 7 + 2 (-x) ?? 2x - 1 = 7 - 2x 4x = 8 x = 2
Find the sum 3x2 plus 2x plus 3 plus x2 plus x plus 1?
3x2 + 2x + 3 + x2 + x + 1 = 4x 2+ 3x + 4
