120 - 90x = 210
-9x-25=3 -9x=28 9x=-28 x=-28/9
-2x2 + 9x - 12 = 0Then apply the quadratic formula.
9x+6 = 7x+18 9x-7x = 18-6 2x = 12 x = 6
9x + 2 = 12x + 14 -3x = 12 x = -4
120 - 90x = 210
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
-2x2 + 9x - 12 = 0Then apply the quadratic formula.
standard form is y =mx + b 9x - 3y = -12 subtract 9x from both sides -3y = -9x -12 divide both sides by -1 3y = 9x +12 divide both sides by 3 y = 3x +4
no
9x-4 = 7x+8 9x-7x = 8+4 2x = 12 x = 6
9x+6 = 7x+18 9x-7x = 18-6 2x = 12 x = 6
9x + 2 = 12x + 14 -3x = 12 x = -4
In this equation, x=6.
9x-11 = 6x+1 9x-6x = 1+11 3x = 12 x = 4
