document.write( "Question 515072: Suppose we describe an equation as equality between functions f(x) = g(x). How do we interpret solutions to equations graphically? Create an example to use in your explanation. What is a solution to an equation?\r
\n" ); document.write( "\n" ); document.write( "I know a \"solution\" to one equation means \"where does it cross the x-axis, if anywhere\". This mean what are the value(s) of x when y=0, since y=0 is the definition of the x-axis. Also a \"solution\" to 2 or more equations means where do they cross each other or where do they have the same value. I just unsure of how the equality between the two functions affects this? I'm just confused thanks for the help!

You're not confused. If two functions have the

\n" ); document.write( "meet at the point of the solution.
\n" ); document.write( "------------------------
\n" ); document.write( "y = 2x+3
\n" ); document.write( "y = x -4
\n" ); document.write( "---
\n" ); document.write( "2x+3 = x-4
\n" ); document.write( "x = -7
\n" ); document.write( "---
\n" ); document.write( "Solve for \"y\":
\n" ); document.write( "y = x-4
\n" ); document.write( "y = -7-4 = -11
\n" ); document.write( "y = -11
\n" ); document.write( "Solution: (-7,-11)
