Practice 1 – Solve a few easy inequalities

Step 1: Make the “x” term stand alone by moving numbers.

x – 17 < 20 ( add 17 to both sides)

x – 17 + 17 < 20 + 17

x < 37

Any number less than 37 is a solution of this inequality.

Video Explanation :

Step 1: Make the “x” term stand alone by moving numbers.

12 < 18 + x ( subtract 18 from both sides)

12 – 18 < 18 + x – 18

-6 < x

Any number greater than – 6 is a solution of this inequality.

Step 1: Make the “x” term stand alone by moving numbers.

42 + x < 31 ( subtract 42 from both sides)

42 + x – 42 < 31 – 42

X < -11

Any number smaller than – 11 is a solution of this inequality.
