Question

How do you solve `-7 = 1 + 2/3n`?

Answer 1

`n= 9`

Explanation:

Given: `" " -7= 1 + 2/3 n`

Step 1: Subtract 1 to both side to get

`7 color(red)(-1) = color(red)(-1) + 1 +2/3 n`
`6 = 2/3 n`

Step 2: Multiply by the reciprocal to both side of the equation to get

`6color(blue)((3/2)) = color(blue)(3/2) 2/3n`
`((cancel2*3)/1)color(blue)((3/cancel(2)) = color(blue)(cancel(3/2) (cancel(2/3))n`

`9= n`

Answer: `n= 9`
