Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "times", "equals". Assuming that the equation is: -5x (9-4x) = 12 then: 20x2 - 45x -12 = 0 a x2 + bx + c = 0 Accordingly, a = 20, b = -45, c = -12 x = [ 45 +- (-45 x-45 - 4 x 20 x -12)1/2]/2 x 20 = [45 +- (54.635)]/40 x = [45 +54.635] / 40 or [45-54.635]/40 x = 2.491 0r x = - 0.241
15 x 3 = 45, 12 x 2 = 24, 45 + 24 = 69
