[2/(3/4)]/6 = (2/1 x 4/3)/6 = (8/3)/(6/1) = 8/3 x 1/6 =8/18 = 4/9 ≈ 0.44
6a - 4 = -2(+ 4 on both sides)6a = 2(divide both sides by 6)a = 2/6a = 1/3
-7x + 6 + 7x - 2 = 4
4!/(2!*2!) = 4*3*2*1/(2*1*2*1) = 6 4!/(2!*2!) = 4*3*2*1/(2*1*2*1) = 6 4!/(2!*2!) = 4*3*2*1/(2*1*2*1) = 6 4!/(2!*2!) = 4*3*2*1/(2*1*2*1) = 6
5x-2 = 3x-6 5x = 3x - 6 +2 5x = 3x - 4 5x - 3x = -4 2x = -4 x = -2
