It's like being on a treasure hunt, with 'x' being the treasure, and the rest of the equation the obstacles. To isolate 'x', you'll need to perform the same operations on both sides of the equation. For instance, if you subtract 7x from both sides, you're essentially moving the obstacles out of the way to reveal your treasure.

Inverse Operations

Inverse operations are like superpowers that help you solve equations quickly and accurately. Addition has subtraction as its inverse, and multiplication has division. To use these superpowers, first, identify the inverse operation of the one applied to 'x'. Then, perform this operation on both sides of the equation. For example, if you have 2x - 7 = 5, you'll first add 7 to both sides, then divide both sides by 2 to isolate 'x'.

Equations and Inequalities

While equations deal with equality, inequalities explore the relationships between numbers that are not equal. Instead of an '=' sign, you'll find '>', '

Checking Your Work: Substitution

After solving a linear equation, it's crucial to check your work. Substitution is a simple and effective method for this. Once you've solved for 'x', substitute the value back into the original equation. If the equation holds true, you've successfully solved it. If not, you might have made a mistake in your calculations. This is like testing a recipe; if the final dish tastes as expected, your cooking was spot on!
