7x≥56

x≥8

Answer 2

The solution set of inequality is $x\in\{8,\;9,10,\;11,\;,...........\}$.

Given:

The given inequality is,

$7x+2\geq58$

According to question,$7x+2\geq58$

Subtract $2$ to both side we get:

$7x+2-2\geq58-2\\ 7x\geq56$

Now, divide whole equation by $7$ we get

$\frac{7x}{7}\geq\frac{56}{7} \\\;\;x\geq8\\x\in\{8,\;9,10,\;11,\;,...........\}$

Hence, solution set of inequality is $x\in\{8,\;9,10,\;11,\;,...........\}$.
