Question

Give the property that justifies each step.7n – 16 = 47Given7n - 16 + 16 = 47 + 167n = 631n = 9

Answer 1

We are given the equation

`7n-16=47`

We can add or subtract the same number on each side of the equation, in this case, we add 16

`7n-16+16=47-16`
`7n=63`

We can divide by the same number on each side of the equation

`(7n)/(7)=(63)/(7)`
`n=9`

And thus we solve the equation
