if 9 - 2x = 35
then 9-2x-9 =35-9
-2x = 26
we want make 'x' subject of this equation then we divide both sides by -2
-2x/-2 = 26/-2
x = -13
If: 9-2x = 35 Then: -2x = 35-9 => -2x = 26 So: x = -13
6 + 2x = 5x + 9 , 6 - 9 = 5x - 2x , -3 = 3x , x = -1
6 2(6) + 3 = 9
3x2 + 2x + 2 = 0 Can not be factored. You can however solve it for x: 3x2 + 2x = -2 x2 + 2x/3 = -2/3 x2 + 2x/3 + 1/9 = -2/3 + 1/9 (x + 1/9)2 = -5/9 x + 1/9 = ±√(-5/9) x = -1/9 ± i√(5/9) x = -1/9 ± i√5 / 3 x = -1/9 ± 3i√5 / 9 x = (-1 ± 3i√5) / 9
6x-7=8x+9 bring the x over -7=2x+9 take the 9 over -16=2x divide both sides by 2 x=-8
