Question

solve for (x) and graph the solution on the number line below.

(63 < 7x)

answer

inequality notation:

Explanation:

Step1: Isolate the variable x

Divide both sides of the inequality $63 < 7x$ by 7.
$\frac{63}{7}<\frac{7x}{7}$

Step2: Simplify the inequality

$9 < x$ or $x>9$

Answer:

Inequality Notation: $x > 9$
To graph on a number - line: Draw an open circle at 9 (because 9 is not included in the solution) and draw an arrow to the right to represent all numbers greater than 9.
