make a sketch of their graphs and see where they intersect.
Here is one of the best websites for graphing ...
http://rechneronline.de/function-graphs/
enter:
x for the first graph
tan(x) for the second graph
change "Range x-axis from" -20 to 20
change "Range y-axis from" -50 to 50
As you can see there will be an infinite number of solutions
the obvious one is x=0
the next one is
another is appr 10.904
check:
y = x = 10.904
y = tan(10.904) = 10.9
