Be more specific Please.
As in
X + 9 = 18 + X?
x = 7
The answer to the problem of 13 equals -4x plus 9 is x equals -1.
Two possibilities 1. (9+2) X 5 = 11 X 5 = 55 2. 9 + 2X5 = 9 + 10 = 19 Does your problem have parenthesis aka "()" symbols in it? ?
Since the problem has 4 terms, first you factor x cubed plus 9x squared, then you factor 2x plus 18. So when you factor the first two term, you would get x sqaured (x plus 9). Then when you factor the last two terms and you get 2 (x plus 9). Ypure final answer would be (x squared plus 2)(x plus 9)
4x2+49x+90 = (4x+9)(x+10) when factored
x(x + 9)(x + 1)
They are two terms of an expression in the form of: x+9
If: x+9+5x = 21+2x Then: x = 3
1/3x + 6 = 9 Restating the problem x + 18 = 27 I multiplied by 3 x = 9 I subtracted 18 from 27
3x + 9
(x+1)(x+9)
The math problem of x plus 23 is incomplete and there is not an answer for it. More information is needed for this problem.
