%{
ax+by=c....equ(1)
dx+ey=f....equ(2)
A=[a b;d e]
B=[c f]
sol=A/B
x=sol(1)
y=sol(2)
example
3x-9y=-42....equ(1)
2x+4y=2......equ(2)
%}
A = [3 -9;2 4]
b = [-42;2]
%Solve Ax=b as A\b
sol=A\b;
x=sol(1)
y=sol(2)

The equations doesn't correspond to the equations posted by the OP, by the way the correct solution had been answered and accepted 8 years ago.
