Properties of Inequation or Inequalities<\/h2>\n

The six different properties of linear inequalities or linear inequation are mentioned here. These properties describe how arithmetic operations show the effect on the linear inequations.<\/p>\n

Property I<\/strong><\/p>\n

The inequation remains unchanged if the same quantity is added to both sides of it.<\/p>\n

Example:<\/p>\n

x – 3 < 4<\/p>\n

Add 3 to the both sides<\/p>\n

= x – 3 + 3 < 4 + 3<\/p>\n

= x < 7<\/p>\n

Property II:<\/strong><\/p>\n

The inequation remains unchanged if the same quantity is subtracted from the both sides of the inequation.<\/p>\n

Example:<\/p>\n

x + 3 < 4<\/p>\n

Subtract 3 from both sides<\/p>\n

x + 3 – 3 < 4 – 3<\/p>\n

x < 1<\/p>\n

Property III:<\/strong><\/p>\n

The inequation remains unchanged if the same positive number is multiplied to both sides of it.<\/p>\n

Example:<\/p>\n

x\/3 > 5<\/p>\n

multiply 3 to both sides<\/p>\n

= x\/3 x 3 > 5 x 3<\/p>\n

= x > 15<\/p>\n

Property IV:<\/strong><\/p>\n

The inequation changes if the same negative number is multiplied to both sides of it. Actually, it reverses.<\/p>\n

Example:<\/p>\n

x\/5 < 6<\/p>\n

multiply -5 to the both sides<\/p>\n

= x\/5 x (-5) < 6 x (-5)<\/p>\n

= -x < -30<\/p>\n

= x > 30<\/p>\n

Property V:<\/strong><\/p>\n

The inequation remains unchanged if the same positive number is divided by both sides of the inequation.<\/p>\n

Example:<\/p>\n

5x > 20<\/p>\n

dividing both sides by 5<\/p>\n

= 5x\/5 > 20\/5<\/p>\n

= x > 4<\/p>\n

Property VI: <\/strong><\/p>\n

The inequation changes when the same negative number is divided by both sides. It reverses.<\/p>\n

Example:<\/p>\n

-3x < 12<\/p>\n

Dividing both sides by -3<\/p>\n

= -3x\/-3 > 12\/-3<\/p>\n

= x > -4<\/p>\n

Solved Examples on Properties of Linear Inequalities<\/h3>\n

Example 1.<\/strong><\/p>\n

Write the inequality obtained for each of the following statements.<\/p>\n

(i) On subtracting 9 from both sides of 21 > 10.<\/p>\n

(ii) On multiplying each side of 8 < 12 by -2.<\/p>\n

Solution:<\/strong><\/p>\n

(i) We know that subtracting the same number from both sides of inequality does not change the inequality.<\/p>\n

21 – 9 > 10 – 9<\/p>\n

= 12 > 1<\/p>\n

(ii) We know that multiplying each side of an inequality by the same negative number reverses that inequality.<\/p>\n

= 8 x -2 < 12 x -2<\/p>\n

= -16 < -24<\/p>\n

= -16 > -24<\/p>\n

Example 2.<\/strong><\/p>\n

Find the inequality obtained for the following statements.<\/p>\n

(i) On adding 2 to both sides of 8 < 56<\/p>\n

(ii) On dividing each side of 8 < 56 by -16.<\/p>\n

Solution:<\/strong><\/p>\n

(i) We know that adding the same number to both sides of inequality does not change the inequality.<\/p>\n

8 + 2 < 56 + 2<\/p>\n

= 10 < 58<\/p>\n

(ii) We know that dividing each side of an inequality by the same negative number reverses that.<\/p>\n

8\/-16 < 56\/-16<\/p>\n

= -1\/2 > -7\/2<\/p>\n

Example 3.<\/strong><\/p>\n

Write the inequality obtained for the following statement.<\/p>\n

On multiplying each side of 18 > 8 by 5.<\/p>\n

Solution:<\/strong><\/p>\n

We know that multiplying each side of an inequality by the same positive number does not change the inequality.<\/p>\n

18 x 5 > 8 x 5<\/p>\n

= 90 > 40<\/p>\n","protected":false},"excerpt":{"rendered":"
