When x equals 8 what is the value of 3x-x?
If x equals 8, then 3x equals 24. 24-x would equal 16.
What does 3x 2 equal?
If you mean: -2(3x-3) = 7x-2 then the value of x works out as 8/13
3x equals 1x plus 8 what does x equal?
3x = x+8 so 3x-x = 8 hence 2x = 8 and so x = 4
What is 3x - 2 equals x plus 8?
3x-2=x+8 (+2) 3x=x+10 (-x) 2x=10 (/2) x=5
How do you solve 3x2 plus 10x equals 8 by factoring?
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. ■

What does 3x x equal?
3x^2
How do you solve 9x squared plus 18x minus 16 equal 0?
9x2 + 18x - 16 = 0 ⇒ (3x - 2)(3x + 8) = 0 ⇒ 3x - 2 = 0 → x = 2/3 or 3x + 8 = 0 → x = -22/3
What is 3x - 2 equals x plus 8?
3x-2=x+8 (+2) 3x=x+10 (-x) 2x=10 (/2) x=5

If 3x equal 7- 5x then x equal?
3x = 7-5x 8x=7 x = 7/8 x = 0.875
What is the solution of y x 4 y 3x 8?
If you mean: y = x+4 and y = 3x+8 then x = -2 and y = 2
3x plus 8 equals 20-3x what is x?
3x + x + 8 = 204x + 8 = 204x = 12x = 3
What expression is equivalant to -2 x-2?
2(3x + 4) = 6x + 8 3(x - 5) = 3x - 15 6x + 8 - 3x + 15 = 3x + 23
What does X equal in 3x equals 2?
3x=2 Divide the x over and you get 3 divided by 2 x=3/2
