8. Solve the following system of five linear equations: 3u+1.5v+w+0.5x+4y2u+v+4w3.5x+2y6u3v+2w+2.5x+yu+4v3w+0.5x2y3u+2vw+1.5x3y=11.75=19=23=1.5=3.5 Solution: u=4,v=2.5,w=4,x=1, and y=2 9. The electrical circuit shown below consists of resistors and voltage sources. Given: V1=12V,V2=24V,R1=20,R2=12,R3=8,R4=6, and R5=10. Find equations by hand then solve in MATLAB. Only solve for the 4 mesh currents as we will review in lab (if you did not take Circuits last semester); currents are drawn clockwise. Solution: top: 1.2667A, left middle: 1.7619A, right middle: 0.5587A, and bottom: 0.2095 A
