//KVL over the supermesh, we get eqn-1 -20+4(i1)+8(i2)=0
//Vx=2(i2) ohm's law
//writing an expression for the source current in terms of mesh currents and substituting Vx from above, we get eqn-2 (1/2)i2=i2-i1
//Putting eqn-1 and eqn-2 in standard form 4(i1)+8(i2)=20 and i1-(1/2)i2=0
//solving for currents in matrix method(Ax=b)
A=[4,8;1,-1/2]; //coeffcient matrix
b=[20;0]; //constant matrix
