Amit solved the equation StartFraction 5 over 12 EndFraction = Negative StartFraction x over 420 EndFraction for x using the steps shown below. What was Amit’s error? StartFraction 5 over 12 EndFraction = Negative StartFraction x over 420 EndFraction. StartFraction 5 over 12 EndFraction (420) = Negative StartFraction x over 420 EndFraction (420). X = 175. Amit should have multiplied both sides of the equation by StartFraction 5 over 12 EndFraction. Amit should have multiplied both sides of the equation by StartFraction 12 over 5 EndFraction. The product of StartFraction 5 over 12 EndFraction and 420 is not equal to 175. The product of StartFraction 5 over 12 EndFraction and –420 should have been the value of x.
