3x + 9
-5x + x + 9 = -4x + 12 -4x + 9 = -4x + 12 9 = 12 This equation has no solution.
4x + 2 = 3x + 9 x + 2 = 9 x = 7
5x = 4x + 9 x = 9
4x+5 = -9 4x = -9-5 4x = -14 x = -3.5
If you mean: x+4x--9 = x+1 then 4x = -8 and x = -2
4x3 + 16x2 - 180x = 4x(x2 + 4x - 45) = 4x(x + 9)(x - 5)
4x+9=25 4x=16 x=4
4x-9(x plus 1)7-5x?
3+6x = 4x+9 6x-4x = 9-3 2x = 6 x = 3
Let's see... 4x+10=x+37 x = 9
4x + 9 = 254x = 25 - 94 x = 16x= 16/4x= 4
The solution of 4x plus 3y -9 and x -3 is; 5x+3y-3.
