Solving simultaneous equations without martix method

Hi

What is simply way to solve for a simultaneous equation like below without the uses of matrix method. I was hoping to implement to a hard equation as below is just a example.

x+y=10
x+2*y=15

You would most likely have to use the Symbolic Math Toolbox:

syms x y 
Eq1 = x + y == 10;
Eq2 = x + 2*y == 15;
[x,y] = solve(Eq1, Eq2)

x =
5

y =
5
