It depends on what it is meant to be equivalent to!
It is equivalent to: 3x+6+5 = 3x+11
3x-3x+4x^2+8x=4x^2+8x
3x + 2x - 8x + 2x = -x
It is equivalent to: 6x^2 -8x -8
5x+8x+3x-2x = 14x
-8x
3x+5y+8x+2y combine 3x and 8x to get 11x 11x+5y+2y combine 5y and 2y 11x+7y is the answer.
-3x + 1
8x - 23= 3x + 2 +23 +23 8x=3x + 25 -3x -3x 5x=25 x=5 the answer is X=5
3x + 6x - x= 8x
8x + 6 = 3x - 4 8x = 3x - 4 - 6 8x = 3x - 10 8x - 3x = -10 5x = -10 5x/5 = -10 x = -10/5 x = -2
4 + 8x
