<prompt> Ndege P imekadiriwa kwamathbfv anzapmatrix 1 6 7 mwishopmatrix t anzapmatrix 2 -1 -1 mwishopmatrix s anza pmatrix 2 -3 -5 mwishopmatrix,na mstari L umeainishwa namathbfw anzapmatrix 7 4 1 mwishopmatrix u anzapmatrix 3 0 -1 mwishopmatrix.Tafuta makutano ya ndege P na mstari L.  <response>: Kuweka parameterizations kuwa sawa, tunapataanzaalign1 2t 2s 7 3u, 6 - t - 3s 4 7 - t - 5s 1 - u.endalignKutatua mfumo huu, tunapata s 1, t -1, na u -2. Kwa hivyo, hatua ya makutano ni beginpmatrix 1 4 3 mwishopmatrix.
