It means you want to have X on one side of the equation and the other side be as simple as possible.
Good example.
X = 2
Bad examples
X= 5X + 2
X= 8/2
See in the bad example X is on both sides of the equation? In the second bad example, the right side of the equation can be simplified further.

When you have an equation such as 2x - 3=45, or any equation with a variable (in this case x), you simplify the equation by isolating the variable. In my example, you add three to both sides, giving you 2x=48. Then you divide both sides by 2, giving you x=24.
Basically you play with the numbers until you only have a variable on one side.

ex. resolve equation 3x - 8 = 7 3x - 8 is an expression 3x - 8 with the equivalent sign to a # supplies us an equation 3x - 8 = 7 is an equation with one varible, it extremely is x to isolate the variable, x, we could upload 8 to the two facet of the equation. 3x - 8 + 8 = 7 + 8 as a results of fact it extremely is an equation each and everything we do on one facet we could do to the facet of the equivalent sign for balancing 3x = 15 We nonetheless could do away with the three in front of the x, 3 writen next to the x ability that it extremely is multiplying x, as a thank you to undo a multiplication we divide the two facet by utilising 3 3x/3 = 15/3 ---> x=5 We basically remoted, solved, for x. 3x - 8 = 7 <<----- This equation is aking you what extensive type, x, multiply 3 and minus 8 equals 7 And x = 5 is our answer The extensive type 5 multiply 3 minus 8 equals 7.

We must first make sure we have the variable only on one side. It does not matter which side we choose. Some people prefer to always move the variable to the left side while others try to make sure they don’t have a negative coefficient. There is no “always correct” method. The most important thing is to know how to get the variable only on one side.

it means to leave the variables required to be found on one side and the other terms on the other.
general form of a linear eq. is ax + b = 0, where a,b are Real nos. and a not equal to 0.
if we isolate the variable on one side, then the solution is
x= (-b/a)

5x = 2+7
Consider the example above. it is a linear equation.
You need to find the value of X.
or it is stated as
x=?? <===== X is isolated here right? so this is your goal. you need to free everything that is with the x variable so that you can find out that X is equal to .....

i gues it means to take the variable to one side of the equation and have the consonants on the other side
as in x+4=8
now taking the 4 the other side thats is
x=8-4
so the variable x is on one side and the answer is 4

i think it means trying to get the x or y variable alone... look at this website maybe it will help you :)
