You need to isolate the variable you want to solve for, on one side of the equation. This involves getting rid of everything else. Note that what you do on one side of the equation, you also have to do on the other side. "Getting rid" of everything else basically means doing the inverse of the operation shown.
Example:
2x + 3 = 21
You might start by getting rid of the 3. For this, you subtract 3 on both sides. Subtracting 3 is the inverse of the operation shown in the equation, adding 3.
2x + 3 - 3 = 21 - 3
2x = 18
Next, you get rid of the 2. Once again, since in the equation there is a multiplication by 2, you divide by 2 - the inverse operation. In this case, you divide by 2 on each side:
2x/2 = 18/2
(2/2)x = 18/2
x = 9

Get a variable alone on one side of an equation or inquality in order to solve the equation or inequality?
To isolate a variable in an equation or inequality, you need to perform inverse operations to both sides. Start by eliminating any constants added or subtracted from the variable, followed by dividing or multiplying to remove coefficients. Ensure to maintain the equality or inequality by performing the same operations on both sides. Finally, simplify the expression to get the variable alone on one side.
