12x = 36

-12x = 72 Divde both sides by -12 to find the value of x: x = -6
Without an equality sign it is not a straight line equation but if you mean 9y-12x-72 = 0 then y = 4/3x+8
x = -6
2x2 - 72 would be factored into (2x - 12)(x + 6) or (2x + 12)(x - 6) To double check, multiply each pair: (2x - 12)(x + 6) = 2x2 + 12x - 12x - 72 = 2x2 - 72 (2x + 12)(x - 6) = 2x2 - 12x + 12 x - 72 = 2x2 - 72
The given expression has no solution because without an equality sign it can't be considered to be an equation.

No solution. Multiply second equation by 3 and get 12x + 6y = 0 but already stated 12x + 6y = 9...
