x_p, y_p, z_p=(4, 5, 2)
x_1, y_1, z_1=(8, 9, 5)
x_2, y_2, z_2=(2, 5, 1)
x_3, y_3, z_3=(6, 1, 3)
and my three equations are
eqn1 = sqrt((x(s)-x_p)^2+(y(s)-y_p)^2+(z(s)-z_p)^2)-sqrt((x(s)-x_1)^2+(y(s)-y_1)^2+(z(s)-z_2)^2)-(c*t_1)
eqn2 = sqrt((x(s)-x_p)^2+(y(s)-y_p)^2+(z(s)-z_p)^2)-sqrt((x(s)-x_2)^2+(y(s)-y_2)^2+(z(s)-z_2)^2)-(c*t_1)
eqn3 = sqrt((x(s)-x_p)^2+(y(s)-y_p)^2+(z(s)-z_p)^2)-sqrt((x(s)-x_3)^2+(y(s)-y_3)^2+(z(s)-z_3)^2)-(c*t_1)
where only x(s), y(s), z(s) are unknown are rest all are known

This is a duplicate of Walter already gave an answer. Comment on that question if there is an issue. As you mentioned that there is an error, then also paste the error message.
