Question

1/2 n + 3 < 5 how would it be shown on a graph

Answer 1

To solve this inequality we need to isolate the variable "n" on the left side.

`(1)/(2)n<5-3`

Since there was a "+3" on the left side we needed to change its side, by inverting the number's signal.

`\begin{gathered} (1)/(2)n<2 \\ n<2\cdot2 \\ n<4 \end{gathered}`

Since the variable we need to calculate was multiplying "1/2" we needed to multiply both sides by 2 in order to find its value. The solution is n < 4.
