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
