Answer #1

Code:

clc
clear

syms I1 I2 I3 I4 I5 I6 I7
eqns = [3*I1 + 4*I2 + 2*I3 - I4 + I5 + 7*I6 + I7 == 42,
2*I1 - 2*I2 + 3*I3 - 4*I4 + 5*I5 + 2*I6 + 8*I7 == 32,
I1 + 2*I2 + 3*I3 + I4 + 2*I5 + 4*I6 + 67 == 12,
5*I1 + 10*I2 + 4*I3 + 3*I4 + 9*I5 - 2*I6 + I7 == -5,
3*I1 + 2*I2 - 2*I3 - 4*I4 - 5*I5 - 6*I6 + 7*I7 == 10,
-2*I1 + 9*I2 + I3 + 3*I4 - 3*I5 + 5*I6 + I7 == 18,
I1 - 2*I2 - 8*I3 + 4*I4 + 2*I5 + 4*I6 + 5*I7 == 17];
[A,b] = equationsToMatrix(eqns);
I_VEC = A\b;
disp('Currents:');
I = eval(I_VEC);
disp("I1: "+num2str(I(1)));
disp("I2: "+num2str(I(2)));
disp("I3: "+num2str(I(3)));
disp("I4: "+num2str(I(4)));
disp("I5: "+num2str(I(5)));
disp("I6: "+num2str(I(6)));
disp("I7: "+num2str(I(7)));

Output:

Currents:
I1: -21.6759
I2: 19.4411
I3: -29.5797
I4: -42.7739
I5: 19.472
I6: 5.0906
I7: -9.458
