To solve inequalities, you are trying to get the X variable by itself with a positive charge of 1. If the coefficient in front of it is negative, you must flip the sign in the other direction.
Example:
-3x < 9
divide each side by a negative 3. This means we have to flip the sign.
Hey! a+5=7 means that a is the variable, while seven is the answer. My technique is like this: 7-5=2 You need to subtract the numbers you already have. This only works for addition! Hope this helps :) !
