The given equation is either linear or equivalent to a linear equation. Solve the equation. (If there is no solution, enter No solution. If all real numbers are solutions, enter REALS.)

To solve an equation that is linear or equivalent to a linear equation, first, you’d simplify it to isolate the variable on one side. This often involves combining like terms and using inverse operations. If you end up with an identity like , that means all real numbers are solutions (REALS). If a contradiction arises like , it indicates there is no solution.

When encountering these equations, be cautious of common pitfalls—like forgetting to distribute or correctly combine like terms. A diligent check on your work can save you from those sneaky errors!
