Clara solved the equation 7 3 x = − 2 3 as shown. 7 3 x ( 3 7 ) = − 2 3 ( 3 7 ) x = −14 What is Clara’s error? Clara should have divided by StartFraction 3 over 7 EndFraction. Clara should have added StartFraction 7 over 3 EndFraction. Clara should have multiplied by StartFraction 7 over 3 EndFraction. The solution is Negative StartFraction 2 over 7 EndFraction, not –14.
