Provide the matlab commands needed to determine the solution to the following system of equations in a matlab program (linearequation. m). use matlab to check the solution by multiplying coefficient matrix a with the solution vector x, to produce b. that is, ax = b. w + 3x + 4y = 31 2w + x + 3y + z = 27 9x + 7y + 2z = 72 4w + 3x + 2y + 2z = 27.

Ihave a singular monitor that is a tv for my computer. recently, i took apart my computer and put it back together. when i put in the hdmi cord and booted the computer to see if it worked, the computer turned on fine but the screen was blue with "hdmi no signal." i've tried everything that doesn't require buying spare parts, any answer is appreciated!
