1. ( x - 5 ) / x   -  1 = ( x + 3 ) / x    / · x ( we will multiply both sides by x ) x - 5 - x = x + 3 - x = 3 + 8 - x = 8 x = - 8 Answer: D ) 8 2. 2/(8 x²) = 1/ 8 x   / · x 2 / 8 x = 1 / 8 8 x = 16 x = 16 : 8 x = 2 Answer: D ) 2 3. ( x + 4 )/ x  + 1 = ( x + 6 ) / x              / · x x + 4 + x = x + 6 x = 6 - 4 x = 2 Answer: B ) 2 4.  1 / 6 = 3 / ( x + 12 ) x + 12 = 18 x = 18 - 12 x = 6 Answer: A ) 6
