Question

Solve for the value of $\mathrm{x}$, where $4x+1\ge 17,wherex\in N$

Answer 1

In-equality:

Given, $4x+1\ge 17,wherex\in N$

$\Rightarrow 4\mathrm{x}+1-1\ge 17-1$ (subtracting $1$on both sides)

$\Rightarrow 4\mathrm{x}\ge 16$

$\Rightarrow \frac{4\mathrm{x}}{4}\ge \frac{16}{4}$ (dividing by $4$ on both sides)

$\Rightarrow \mathrm{x}\ge 4$, where $\mathrm{x}$ is a set of natural numbers.

$\Rightarrow \mathrm{x}=\left\{4,5,6,7,8..........\infty \right\}$ , which is the required solution.
