The expression you provided, "3x x-2x 8 3x x," appears to be a combination of terms and operators that may not be clearly defined. If you meant to describe an algebraic expression involving multiplication and possibly addition or subtraction, please clarify the intended operations and structure. For example, if you meant "3x - 2x + 8 + 3x," the result would be simplified to "4x + 8."

3x² + 10x = 8 Rewrite as: 3x² + 10x - 8 = 0 The only way to get 3x² is 3x and x (3x + -- ) (x + --) The factors of 8 are {1 2 4 8} so the answers must be a pair of them. With 4 factors, and a negative sign (the -8), there are only 8 ways this can be written: (3x + 1)(x - 8) = 3x² - 23x - 8 (3x + 2)(x - 4) = 3x² -10x - 8 (almost) (3x + 4 )(x - 2) = 3x² - 8x - 8 (3x + 8)(x - 1) = 3x² +5x - 8 (3x - 1)(x + 8) = 3x² +23x - 8 (3x - 2)(x + 4) = 3x² + 10x -8 ◄ Success! (3x - 4)(x + 2) = 3x² +2x - 8 (3x - 8)(x + 1) = 3x² -5x - 8 Trial and error, error, error, is the key to this kind of problem. Seeing the -10x early can point you to see that maybe changing the signs can work. ■
3x + 8 = 8 Therefore, 3x = 0 x = 0/3 x = 0
3x - x = 3*8 - 8 = 24 - 8 = 16
3x = x+8 so 3x-x = 8 hence 2x = 8 and so x = 4
IF 3X-1=11, WHAT IS THE VALUE OF X 2 + X?
2x+x2x = x+xso 2x+x isx+x+x = 3x
-if3X-1=11,what is the value of X^2+X?

3x + 8 = 8 Therefore, 3x = 0 x = 0/3 x = 0
3x + x + 8 = 204x + 8 = 204x = 12x = 3
3x - x = 3*8 - 8 = 24 - 8 = 16
3x = x+8 so 3x-x = 8 hence 2x = 8 and so x = 4
If x equals 8, then 3x equals 24. 24-x would equal 16.
3x + 8 = 20 3x = 20 - 8 3x = 12 3x = 12/3 x = 4
If you mean: y = x+4 and y = 3x+8 then x = -2 and y = 2
