If 5 x equals 9 plus 2x then x equals?
4x2 - 12x + 9 = 5; whence, 2x - 3 = ±√5, and 2x = 3 ±√5. Therefore, x = ½ (3 ±√5).
if 2x+3=9 then 2x=6 so x=3
2x+1 = 9 2x = 9-1 2x = 8 x = 4
2x + 1 = -5 so 2x = -6 so that x = -3 Then 3x - 4 = 3*(-3) -4 = -9 - 4 = -13
If 5 x equals 9 plus 2x then x equals?
X equals 2 :)
2x = -x +9
The answer to 1 over 2x plus 13 equals 9 is x equals -8.
4x2 - 12x + 9 = 5; whence, 2x - 3 = ±√5, and 2x = 3 ±√5. Therefore, x = ½ (3 ±√5).
x=-1/2
If x equals 2, then you first write out your equation 2x + 5 = y. You then fill out 2(2) + 5 = y. 2 x 2 = 4, so then 4 plus 5 equals 9.
5x+18 = 2x+9 5x-2x = 9-18 3x = -9 x = -3 and y = 3
5x + x - 6x + 2x = 2x
x equals 19
no...why would it.... it equals 2x+9
if 2x+3=9 then 2x=6 so x=3
