5p-9=2p+12
+9 +9
5p= 2p+21
-2p -2p
3p/3=21/3
p=7
6/(2/3) = 6*3/2 = 18/2 = 9
There are (9) - 2/3 in 6
<h3>[Learning] How to solve a one-variable-inequality?</h3>
To solve a one-variable-inequality, isolate the variable on one side of the inequality. This can be done by using the <u>four mathematical operations.</u>
What is the four mathematical operations?
The<em> </em><u>four mathematical operations</u> include the following:
- Addition
- Subtraction
- Multiplication
- Division
These operations can be used to solve equations, inequalities, and more.
<h3>[Solving] Simplifying the inequality:</h3>
Given inequality:
As stated in the previous section, let's isolate the variable (c) using the four mathematical operations. Clearly, we have to add both sides by 12 of the inequality as "c" is being subtracted by 12. Therefore, we get:
- ⇒ c – 12 + 12 > –1 + 12
- ⇒ c > –1 + 12
Simplify the right-hand-side to obtain the simplified inequality:
Therefore, option B is the correct/best choice.
