INEQUATIONS
Inequality signs

> is greater than
≥ is greater than or equal to < is less than ≤ is less than or equal to |
SOLVING INEQUATIONS
Balance an inequation by adding/subtracting the same value
from each side of the inequation or by multiplying or dividing
each side of the inequation by the same value.
WORKS - JUST LIKE EQUATIONS. (Revise Equations)
The only tricky bit is if you multiply or divide throughout
by a negative number you need to flip the sign.

Examples
x + 4 > 9
subtract 4 from each side x > 5 |
y - 66 ≤ 11
add 6 to both sides y ≤ 17 |
5p6 > 35
divide both sides by 5 p > 7 |
k ÷ 3 ≥ 8
multiply both sides by 3 k ≥ 24 |
3t + 2 > 14
subtract 2 from each side 3t > 12 divide both sides by 3 t > 4 |
20 - 8m ≥ 4
subtract 20 from both sides - 8m ≥ -16 divide both sides by - 8 m ≤ 2 |
