4. Consider the following system of equations: 3'1 = #31111 + .3211: + 33113 + 34114. 3'2 = 31121 + .3212: + 33123 + 34124- J's = 31131 + 132132 + (33133 + (34134 3'4 = 31x41 + #32142 + 33143 + 34.344 J's = 31x51 + + 33153 + 34.15:; J's = .31151 + 132162 + 33153 + a. Conyert this system of equations into matrix form. (Hint: \"four response should look like Y = X. There should only be one oolumn In your [3 matrix} In. Assuming that I is invertible, re-write the expression Y = II! to solve for [1. {Hint: Solye only with the symbols of Y, X. and [3. Do not solve with actual matrices}
