Question

(7.01)Corinne solved the equation below:5x = 955x − 5 = 95 − 5x = 90Is Corinne's solution correct? If the solution is incorrect, explain why it is incorrect and show the correct steps to solve the equation.

Answer 1

It is incorrect because it subtracts two terms that are not similar, the solution of the equation is x = 19

Explanation:

We have the following equation:

`5x\:=\:95`

Corinne's mistake is that 5x - 5 cannot be subtracted because these two terms are not like.

It must be solved in the following way:

`\begin{gathered} 5x=95 \\ \\ x=(95)/(5) \\ \\ x=19 \end{gathered}`

The solution of the equation is x = 19
