b) \( 3+3 x-1=x+2+2 x \)

To solve the equation \( 3 + 3x - 1 = x + 2 + 2x \), first, simplify both sides. The left side becomes \( 2 + 3x \), and the right side simplifies to \( 2 + 3x \). Both sides are equal, meaning this equation holds true for all values of \( x \) – it represents a true statement. This means you have an identity, which indicates that any real number can be substituted for \( x \), and the equation will still be valid. Isn't it fascinating when math brings us such universal truths? It’s like finding out a secret that binds everything together!
