Question

Solve the inequality: 9x > 18

Answer 1

9x > 18

x > 18/9

x > 2

Answer 2

Answer:

x > 2

Step-by-step explanation:

9x > 18

In solving this inequality, we divide both sides of the inequality sign by the coefficient of the unknown variable, 9

9x/9 > 18/9

x > 2

An important thing to note in solving an inequality is that when you are dividing an inequality by a negative number, the inequality sign changes that is, a greater than sign, > changes to a less than sign, <.

The solution of the inequality is therefore,

x > 2, read as x is greater than 2
