Question
A compound inequality including “or” has the solutions of ___________.
- Only the first inequality statement
- Only the second inequality statement
- Either of the inequalities
- Both the inequalities
Hint:
This is a question of compound inequalities. A compound inequality means we are given two statements. It is joined using the words “and” and “or”. We have to find the values of the variables satisfying those statements.
The correct answer is: Either of the inequalities
We are asked about the word “or”.
When the word “and” is used, the values of the variables simultaneously satisfy both the inequalities.
If we plot the solutions on a graph, the final graph will be intersection of both the inequalities.
When the word “or” is used, the values of the variables satisfy either of the inequalities.
If we plot the solution graph, the final graph will show solutions of either of inequalities.
So, a compound inequality including “or” has the solutions of either of the inequalities.
Whenever we solve questions of inequality, we have to check for the words “and” and “or”.

What is the solution of 0.2 x -4 - 2x < - 0.4 and 3x + 2.7 <3 ?
The given inequalities are as follows:
0.2x – 4 – 2x < -0.4 and 3x + 2.7 < 3
The word used to join them is “and”. So, we have to find the values of x satisfying both the statements.
When the word “and” is used, the values of the variables simultaneously satisfy both the inequalities.
When the word “or” is used, the values of the variables satisfy either of the inequalities.
We will solve the inequalities one by one.
0.2x – 4 – 2x < -0.4
We will take the variables together and solve them first.
0.2x – 2x – 4 < - 0.4
- 1.8x – 4 < - 0.4
We will isolate the variable by adding 4 to both the sides.
-1.8x – 4 + 4 < -0.4 + 4
- 1.8x < 3.6
Now, we will divide both the sides by -1.8. As we are dividing by a negative number, the inequality will flip.

x > -2
3x + 2.7 < 3
We will isolate the variable by subtracting 2.7 from both the sides.
3x + 2.7 – 2.7 < 3 – 2.7
3x < 0.3
Dividing both the sides by 3 we get,
x < 0.1
Now, the values satisfying the two inequalities are given as follows:
x > -2
x < 0.1
We can combine the solution and write the intersection of the solution as follow:
-2 < x < 0.1
So, the solution is -2 < x < 0.1.
0.2x – 4 – 2x < -0.4 and 3x + 2.7 < 3
The word used to join them is “and”. So, we have to find the values of x satisfying both the statements.
When the word “and” is used, the values of the variables simultaneously satisfy both the inequalities.

- 1.8x < 3.6
Now, we will divide both the sides by -1.8. As we are dividing by a negative number, the inequality will flip.
x > -2
3x + 2.7 < 3
We will isolate the variable by subtracting 2.7 from both the sides.
3x + 2.7 – 2.7 < 3 – 2.7
3x < 0.3
Dividing both the sides by 3 we get,
x < 0.1
Now, the values satisfying the two inequalities are given as follows:
