Reduce it untill the # on the bottom is prime.\n (divide the top AND bottom by 2 untill you get a decimal.)

you have to take the square root of each side, then just simplyfy\n\nx = 1.2472191289247

Working above is good until this step:\n\n2 + 0.8x >0.9(x + 6)\n2 + 0.8x >0.9x + 5.4)\n0.1x > -3.4 ← Symbol error in this line\n\nShould read 0.1x < -3.4\nie x < -34
