Solving set of 2 equations doesn't give a numerical solution

Hi there,

I'm solving a quite simple equation on my computer with the following code:

clc
clear all
close all
syms x y
eq1 = 2*x+3 == 7*y;
eq2 = 2*y*7 == 123 + 2*x;
[x,y] = solve(eq1,eq2,x,y)

Doing this on my laptop (matlab 2014) the solution gives: x = [x] and y = [y]

Running this code on the laptop of my colleague (matlab 2012) gives a solution: x = [117/2] and y = [120/7]

Is there a toolbox that needs to be installed for solving sets of equations or a preference that needs to be checked? I've been able to calculate them in the past but since a week I'm unable of solving them.

Thanks for your help, Alexander

clc
clear all
close all
syms x y
eq1 = 2*x+3-7*y;
eq2 = 2*y*7-123-2*x;
S= solve(eq1,eq2,x,y);
S=[S.x S.y]

or

S=double([S.x S.y])

Thanks for your quick answer. It was very helpful!
