What is the solution to the inequality

Sever21 [200]

Answer:

$x+3>7\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x>4\:\\ \:\mathrm{Interval\:Notation:}&\:\left(4,\:\infty \:\right)\end{bmatrix}$

The solution line graph is also attached.

Step-by-step explanation:

Given

The inequality is given by

$x+3>7$

To determine

What is the solution to the inequality?

Solving the given inequality

$x+3>7$

Subtract 3 from both sides

$x+3-3>7-3$

Simplify

$x>4$

Thus,

$x+3>7\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x>4\:\\ \:\mathrm{Interval\:Notation:}&\:\left(4,\:\infty \:\right)\end{bmatrix}$

The solution line graph is also attached.
