The slopes of the two lines are not equal, therefore the two lines are not parallel and must intersect in a single point. Hence, one solution.
You have two equations where 
is equal to something. Set the two somethings equal to each other and solve for 
. Once you know computing the value of is a simple matter of substitution and arithmetic.
