Answer:
Student's mistake is "5 was not multiplied by −1 "
5(x-1)=5x-5 is the correct equivalent expression
Step-by-step explanation:
Given that a student attempted to generate an equivalent expression by using the distributive property as below
5(x-1)=5x-1
Student's mistake is " 5 was not multiplied by −1 "
For 5(x-1)=5(x)+5(-1)
=5x-5 ( by distributive property a(x+y)=ax+ay )
Therefore 5(x-1)=5x-5 is the correct equivalent expression
