I am trying to find the I1 and I2 (current) of this cicuit using a marix math program.
with the varibles
B1 = +10 V, B2 = +25V, R1 = 12 Ω, R2 = 21Ω, and R3 = 7Ω
I made this bad atempt at it with
I1
I2
B = [10; 25]
I = [I1; I2]
R = [12 21 7]
In = inv(R)*B
I got stuck on it and am not sure I know what I am doing.
any sugestions or examples would help.

Start by deriving two loop equations using the Kirchhoff's voltage law. Next, rewrite the equations in matrix equation form, A*x = B (which you have already learned in Linear Algebra). Then, solve for x (the currents) using the linsolve() command.
