x^2 +9 =x^2 -9 9=-9 No solution
(x-9)(X+8)
If you mean: 9(x-1) = -45 then 9x-9 = -45 and it works out that x = -4
(-6 x 8) + (6 x 9) = 6 is one solution. 6-8 / 6-9 is another solution.
If you mean: x+4x--9 = x+1 then 4x = -8 and x = -2
x=9 is as simple as it gets. The question is the solution.
If you mean x+5y = 4 then (9, -1) is the solution
x - 9 = 0 x - 9 = 0 x - 9 = 0 x - 9 = 0
x^2 +9 =x^2 -9 9=-9 No solution
Assuming you mean x=9-4, x=5
false, there is a solution -34x - 9 = 24 +9 +9 -34x = 33 x= - 33/34 or x = -.970588
X+9=17;8
Suppose x is the smaller number then x+9 is the larger. Then x*(x+9)= 162 or x2 + 9x - 162 = 0 or (x-9)*(x+18) = 0 So: x = 9 giving the solution 9 and 18 OR x = -18, giving the solution -18 and -9
-79
If you mean x+4 = 13 then the value of x is 9
The solution of 4x plus 3y -9 and x -3 is; 5x+3y-3.
