NVM I FIGURED IT OUT

 

 

ive been having trouble with this question i cant see a mistake: 

Ms. C used the distributive property to try to solve: βˆ’2(𝑐 βˆ’ 5) = 28 

a. Check Ms. C’s work. Has she made a math mistake?

b. If your answer to part a is yes, describe the error and correct it – by solving the

problem.

βˆ’2(𝑐 βˆ’ 5) = 28

βˆ’2𝑐 βˆ’ 2(βˆ’5) = 28

βˆ’2𝑐 βˆ’ 10 = 28

βˆ’2𝑐 βˆ’ 10 + 10 = 28 + 10

βˆ’2𝑐 = 38

βˆ’2𝑐

βˆ’2

=

38

βˆ’2

𝑐 = βˆ’19

βˆ’2(c βˆ’5)=28
