8
If you mean: x+4x--9 = x+1 then 4x = -8 and x = -2
There is insufficient information to answer this question. If you mean, what does x equal for: 9 + 6x = 2x ...then the answer is: 9 = 2x - 6x = -4x ...which is equal to: x = -9/4 If you mean, what does x equal for: 9 + 6x + 2x = 0 ...then the answer is: 8x = -9 ...which is equal to: x = -9/8
if x is equal to the square root of 81 then x is ±9 (plus or minus 9)
no...why would it.... it equals 2x+9
It has two equal solutions for x which are x = 2 and x = 2
x = 0
It is a linear algebraic equation where the variable is x. 8x + 9 = 5x + 6 3x = -3 x = -1 < answer Check. 8(-1) + 9 = 5(-1) + 6 -8 + 9 = -5 + 6 1 = 1 They both equal 1.
x^2 + 81
x(x + 9)(x + 1)
It is: (-4)^2 +(-4) -9 = 3 when x is equal to -4
x would equal -1 and y would equal 1
-2x+9=x+1-x........-x-3x+9=1.....-9...-9-3x=-8-3x/-3 | -8/-3\ /........\ /x=8/3
