Get the variable (like x or y) by itself on one side of the equation, without any operations or numbers attached to it.
Use Inverse Operations
Use the opposite operation to get the variable isolated. For example, if there's an addition, do a subtraction, and if there's a multiplication, do a division.
Check Your Answer
Plug your solution back into the original equation to make sure it's true. This is an important step to ensure you got the correct answer.
2x + 3 = 5
Subtract 3 from both sides: 2x = 2. Then, divide both sides by 2: x = 1
