-9x-25=3 -9x=28 9x=-28 x=-28/9
9x + 2 = 12x + 14 -3x = 12 x = -4
9x+6 = 7x+18 9x-7x = 18-6 2x = 12 x = 6
6x + 47 = 9x + 11 6x + 36 = 9x 36 = 3x 12 = x
In this equation, x=6.
If: 12 = 9x+3 Then: 12-3 = 9x And: 9 = 9x So: x =1
9x+27 = -81 9x = -81-27 9x = -108 x = -12
-9x-25=3 -9x=28 9x=-28 x=-28/9
9x + 2 = 12x + 14 -3x = 12 x = -4
no
9x+6 = 7x+18 9x-7x = 18-6 2x = 12 x = 6
6x + 47 = 9x + 11 6x + 36 = 9x 36 = 3x 12 = x
In this equation, x=6.
-2x2 + 9x - 12 = 0Then apply the quadratic formula.
9x-4 = 7x+8 9x-7x = 8+4 2x = 12 x = 6
it equals 13X.
9x + 8 = 6x + 20(- 8 from both sides)9x = 6x + 12(- 6x from both sides)3x = 12(divide both sides by 3)x = 4
