Finding the value for the point two lines cross

I have a graph of two lines that cross each other at some point. I am trying
to find the value at the point the lines cross.

Is there something in Excel that will help with that? On my spreadsheet i
have used the INTERCEPT formula and have two numbers of where each range of Y
axis values cross the X axis. There is one X axis range and twol Y axs
ranges. That tells me where each Y crosses the X. How do I find where the two
Y's cross.

Dare I suggest, given the equations of the lines, algebra?
