Question

Solve the inequality. Graph the solution.

$d+12<19$

Answer 1

Step 1 : Solve the inequality

We have,

$\Rightarrow \mathrm{d}+12<19$

$\Rightarrow \mathrm{d}+12–12<19–12$ [ Subtract $12$ from both sides ]

$\therefore \mathrm{d}<7$

Step 2 : Draw the graph

We have,

$\Rightarrow d<7$

So, the graph is

Hence, the required solution is $\mathrm{d}<7$ and the required graph is shown above.
