1) \( 1 x+3=5 \)

To solve this equation, start by isolating the variable \( x \). First, subtract 3 from both sides to get \( 1x = 5 - 3 \), which simplifies to \( 1x = 2 \). Since multiplying by one doesn’t change the value of \( x \), you can simply conclude that \( x = 2 \). This equation illustrates the basics of algebraic manipulation, where you maintain the balance by performing the same operation on both sides. It’s a handy skill in everything from budgeting to diagnosing issues in your vehicle—having that logical approach makes problem-solving a whole lot easier!
