Question

n-13<2(2n+4)

Answer 1

distribute on the right to start with
\[n-13<4x+8\]

Answer 2

subtract \(n\) from both sides and get \(-13<3n+8\)

Answer 3

subtract \(8\) from both sides to get
\[-21<3n\] and finally divide both sides by \(3\)

Answer 4

Yea, just note that satellite73 actually meant n up there to not x right @satellite73 ?

Answer 5

yeah, of course
