Question

I need help with 17 pls I need an answer in explanation

Answer 1

Step 1

2n = 70

divide both sides by 2

`\begin{gathered} (2n)/(2)=(70)/(2) \\ n\text{ = 35} \end{gathered}`

Step 2

Make a conclusion based on step 1

If n = 3.5

Then substituting for n = 3.5 in the equation

`\begin{gathered} 2(3.5)\text{ =7} \\ 7\text{ is not equal to 70} \end{gathered}`

Therefore n = 3.5 is not a solution of the equation 2n = 70
