2. \( -2=g-9 \)

To solve the equation \( -2 = g - 9 \), you can start by isolating \( g \). Simply add 9 to both sides of the equation, resulting in \( -2 + 9 = g \), which simplifies to \( g = 7 \). So, the solution is \( g = 7 \)! In practical terms, understanding how to solve linear equations like this can be incredibly useful in various fields, from engineering to economics. Whether you're budgeting and need to find break-even points or analyzing data trends, knowing how to manipulate equations can make those tasks far easier!
