One of the coolest tricks in the book is the additive inverse. It's like a magic wand that makes the constant term disappear! For example, if you have 2x + 3 = 5, you can subtract 3 from both sides to get 2x = 2. Voilà! The constant term is gone, and you're one step closer to finding the value of x.
But wait, there's more! The additive inverse is not the only trick up your sleeve. You also have the , which is like a superpower that helps you get rid of the coefficient (the number in front of the variable). For example, if you have 2x = 4, you can divide both sides by 2 to get x = 2. Boom! You've solved the equation, and you're a math rockstar!
