C C -y XIV, § 118] DETERMINANTS 209 118. Solution of Three Linear Equations. Let us con- sider a system of three linear equations between three un- known letters, such as x, y, and z. Any such system is of the form {aix+biy+ciz = di, ch;c+b2y+C2?=d2, a3X+hy+c^=ds, where Oi, &i, ci, di, Oj, ba, etc., represent known numbers (coefficients).
This system may be solved for ...x, y, and z by elimination, as in § 5, but the process is long. We shall here state merely the results, which are as follows (compare with (3) and (4) of §116): dibiCg + d2&3Ci + dabid — dabiCi —dibaC^—d^biCs (2) x= z = ajbiCa + 026301 + a3?>iC2 — agbiCi —aibsd—a^biCa Oicfecs + (hdiCi + asdiC2 — asd^Ci — aidsc^ — a^diCs = } a^2Ci + ai)iCi + a^bid — a^biCi — aibiC2 — (hbiCa fl] Ws -\-(hbsdi-\-a3bidi—asb2di — aib3d2—(hbids dibiCs + oaf'sCi + asbid — agbiCi —aibid— a^iCz It is clear by § 117 that in these values for x, y, and z, each numerator and denominator is the expanded form of a deter- minant of the third order.
