# Revision history [back]

Here's the code I was trying to indicate in my comment plus a little bit extra to address your latest comments. It uses your code and calc314's code. Since you said you wanted it to display the answer, 166.66 you have asked for just the x-value. p1 = plot(20x + 10000, -8,600, ymin = -15, ymax = 30000) p2 = plot(80x, -8,600, ymin = -15, ymax = 30000, color = 'orange') p9 = (p1 + p2) ans=solve(20x+10000==80x,x) x0=ans[0].rhs() y0=80*x0 p3=point( (x0,y0), size=40) p4=text('%s'%x0,(x0+30,y0-1000)) p5=text('(%s,%s)'%(x0,y0),(x0+30,y0-3000)) p9=p1+p2+p3+p4+p5 show(p9) print 'x value of intersection', x0 print 'x value of intersection', n(x0,digits=3)

p1 = plot(20x plot(20*x + 10000, -8,600, ymin = -15, ymax = 30000)
p2 = plot(80x, plot(80*x, -8,600, ymin = -15, ymax = 30000, color = 'orange')
p9 = (p1 + p2)
ans=solve(20x+10000==80x,x)

y0=80*x0
p3=point( (x0,y0), size=40)
p4=text('%s'%x0,(x0+30,y0-1000))
p5=text('(%s,%s)'%(x0,y0),(x0+30,y0-3000))
p9=p1+p2+p3+p4+p5
show(p9)
print 'x value of intersection', x0
print 'x value of intersection', n(x0,digits=3)n(x0,digits=3)


You can, of course, remove the line p5=text('(%s,%s)'%(x0,y0),(x0+30,y0-3000)) and which print statement works best for you.
