3. joe solved the equation 3 + x/2 = 10 and justified each step as shown.

identify joe’s error and fix his mistake.

step / justification

3 + x/2 - 10 given equation

x/2 = 7 multiplication property of equality

x = 14 subtraction property of equality

Joe's answer is justified that his mistake was the property shown to steps 3 and 5 was incorrect but his step3 and step5 are right

That is Step3 : (by using Multiplication Property of Equality )

Step5 :  (by using Subtraction Property of Equality )

The correct properties in steps are given below

Step3 : (by using Subtraction Property of Equality )

Step5 :  (by using Multiplication property of Equality )

This steps and the properties used here are correct.
