22. Of the mathods for solving aystems of equations, which ia the least accurate and may only give an approximate answer? Elimination Graphing None, they are all exact.

Graphing can be a fun and visual way to solve systems of equations, but it often lacks precision, especially when dealing with complex equations or when the solution lies between grid lines. The accuracy of your answer heavily relies on your ability to pinpoint the intersection of the lines, which can be tricky with hand-drawn graphs. For a higher degree of accuracy, using algebraic methods like substitution or elimination can be much more reliable. These methods apply mathematical operations directly to the equations, which means you’ll arrive at an exact solution without the potential pitfalls that come with estimating where two lines cross on a graph. So while graphing is great for visual learners, remember it’s best used alongside other techniques for precise answers!
