solve('v-u-3*t^2=0', 'v'); Undefined function 'solve' for input arguments of type 'char'.

It looks like you are trying to use the symbolic math toolbox, in which case you need to make these variables symbolic:
syms v u t
>> solve(v-u-3*t^2 == 0,v)
ans =
3*t^2 + u

This likely means you do not have the symbolic toolbox. You can check by typing:
