Addition and subtraction are basic ways to work with equations. They help us find the unknown number, called the variable, making math problems easier to solve.
Simplification: These methods make equations simpler. For example, in the equation (x + 5 = 12), you can subtract 5 from both sides. This helps you find (x): [ x = 12 - 5 ] So, (x = 7).
Clarity: Using these methods gives you clear steps to follow, which helps avoid confusion. For example, if you have (2x - 3 = 7), you can add 3 to both sides: [ 2x = 7 + 3 ] This means (2x = 10). Then, you divide by 2 to find (x = 5).
Versatility: You can use these methods in many different situations. This means that once you learn how to add and subtract in equations, you can solve tougher problems with confidence. Overall, getting good at addition and subtraction is very important for understanding linear equations better.
