Igualdade De Matrizes

Matrix equation? 3

Calculate A, B, C and D so that they apply to the same matrix.

3a b + 1 6 5

c + d cd = 2 0

We go there

It is dedicated to written matriculation. But we hear that it is spelled correctly:

| 3a ...... b + 1 | = | 6 ..... 5 |

| c + d ..... cd | = | 2 ..... 0 |

See: This is the same as we gave above, each term gives the same first matrix or the corresponding string term matrix. Once formed, we fear that:

3a = 6. (I)

b + 1 = 5. (II)

c + d = 2. (III)

cd = 0. (IV)

See: By expression (I), we have to:

3 = 6

a = 6/3
