asked • 01/31/20Solve the equation both algebraically and graphically. (Round graphical solution(s) to two decimal places. Enter your answers as comma-separated lists.
If there is no real solution, enter NO REAL SOLUTION.)
x-3=5x+17
Just need help solving graphically
Thanks!

You could graph y = x - 3 and y = 5x + 17 and see where they intersect. The "x-value" of the intersection point is the solution.

thank you

AS written the solution is -5 and would be graphed by a dot on the number line.
Perhaps you have left out a "y"?
Danny L.
nope it just says x-3=5x+17. So would graphically be -5 as well?

Hi Danny L., You would just, on the same piece of graph paper, graph y=x+3 and y=5x+17 . These two lines will intersect at (-5, -8) so x = -5 is a (the) solution. -- Cheers, --- Mr. d. P.S. This is not the ONLY way of showing a graphical solution, just a convenient one. You could, for example, put in values for x, and then graph points using the left part of the equation as "x", and the right part of the equation as "y". Such a line would intersect the line y=x at a point which could be decoded to give the solution. Just sayin'.01/31/20
