solving equations in sas

Question

Is there a function in sas 9.4 similar to solve function in matlab that I can use for solving equations:

syms x sig1 sig2 mu1 mu2;

solve(1/sig1/sqrt(2*pi) * exp(-1/2*((x-mu1)/sig1)^2) == 1/sig2/sqrt(2*pi) * exp(-1/2*((x-mu2)/sig2)^2), x)

Or what would be the most effective way to find intersection point of 2 or more lines in sas.

Thanks

Equation solving is possible in several different environments in SAS.

FCMP: The SOLVE function allows you to solve a previously defined function.
PROC MODEL: The [SOLVE] (http://support.sas.com/documentation/cdl/en/etsug/60372/HTML/default/viewer.htm#etsug_model_sect006.htm) statement allows you to solve a series of NLE for some value(s) when the value of other variable(s) are given.
IML: The SOLVE function can again solve a system of equations, given its representation in matrix form.
