Verified answer

520a + 643m + 633p = 2956 ,

272a + 430m + 35p = 1439,

6a + 7m + 5p = 31

matriz A

520, 643, 633

272, 430, 35

6, 7, 5

det(A) = -176758

matriz Aa

2956, 643, 633

1439, 430, 35

31, 7, 5

det(Aa) = -359231

matriz Am

520, 2956, 633

272, 1439, 35

6, 31, 5

det(Am) = -350066

matriz Ap

520, 643,2956

272, 430, 1439

6, 7, 31

det(Ap) = -174730

a = det(Aa) / det(a) = 259231/176758

m = det(Am) / det(a) = 175033/88379

p = det(Ap)/ det(a) = 87365/88379

pronto

52a + 64.3m + 63.3p = 295.6,

27.2a + 43m + 3.5p = 143.9,

18a + 21m + 15p = 93

a ≅ 2,03233, m ≅ 1,98048, p ≅ 0,988527
