Placing a question mark at the end of a list of expressions or numbers does not make it a sensible question.
Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "times", "equals".
2x+3 = 3x+5 2x-3x = 5-3 -x = 2 x = -2
-3x+2 = 2x-8 8+2 = 2x+3x 10 = 5x x = 2
2x + 2 = 3x - 57 = x
3x+1+2x-2 = 64 3x+2x = 64-1+2 5x = 65 x = 13
3x^2 + x + 2x^2 = 5x^2 + x
2x2 x 3x2 = 6 x4 (2x)2 x (3x)2 = 36 x4
3x + 5x = 2x + 28x = 2x + 26x = 2x = (2/6) = 1/3
2x+3 = 3x+5 2x-3x = 5-3 -x = 2 x = -2
-3x+2 = 2x-8 8+2 = 2x+3x 10 = 5x x = 2
2x + 2 = 3x - 57 = x
3x+1+2x-2 = 64 3x+2x = 64-1+2 5x = 65 x = 13
3x - 2 = 2x + 4 3x - 2x = 4 + 2 x = 6
3x-2 = 2x+3 3x-2x = 3+2 x = 5
2x+3x2 = x (2+3x)
3x^2 + x + 2x^2 = 5x^2 + x
simplify it, 7x-12=x+2+2x-3x 7x=2+12+3x-3x 7x=14 x=2
6x2+19x+10 = (2x+5)(3x+2) Length = 2x+5 Width = 3x+2
