Some thought should give you how to see this is a system of linear equations, two variables.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x=0 for time NOW. Number of bugs is y, and number of months is x.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Ladybugs: slope is 2 and y intercept is 15. The equation is \"y=2x%2B15\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Aphids: slope is \"-3%2F1=-3\". The y intercept is 175. The equation is \"y=-3x%2B175\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "WHEN do these two equations have the same point, or, what is the intersection point?
\n" ); document.write( "\"highlight%282x%2B15=-3x%2B175%29\"
\n" ); document.write( "SOLVE FOR x.
