Simply use the 'Rearranging Formulae' rules, such as adding, multiplying, subtracting, or dividing on both sides to get an integer on one side.
For example, this linear equation:
2x + 4 < 9
4 can be subtracted from both sides.
= 2x < 5
And now it can be divided by 2 on both sides.
= x < 5/2

None. Properties of inequalities are not that relevant when solving equalities.
I DON'T KNOW...... TEACH ME!!?!?!?!?!?!
If you are trying to solve a linear equation and facing difficulty in doing so then try to understand that the variable which u have taken is depending on what factor..and equate it with the constant..by doing this you will be able to solve the equation.
not always,sometimes you have to solve for x
Linear programming can be used to solve problems requiring the optimisation (maximum or minimum) of a linear objective function when the variables are subject to a linear constraints.
