Q:

solve this equation for A: A +[ 11 17 -8 13 ] = [ 0 1 -2 3 ] a11 = a12= a13=a14=

Accepted Solution

A:
Answer:  a₁₁ = -11      a₁₂ = -16       a₁₃ = 6      a₁₄ = -10Step-by-step explanation:"A" represents the following matrix of unknown values [a₁₁    a₁₂      a₁₃     a₁₄][a₁₁    a₁₂      a₁₃     a₁₄]   +    [11    17      -8     13]   =     [0   1      -2     3]a₁₁ + 11 = 0   -->   a₁₁ = 0 - 11    = -11        a₁₂ + 17 = 1   -->   a₁₂ = 1 - 17    = -16                    a₁₃ + -8 = -2  -->  a₁₃ = -2 + 8  = 6                              a₁₄ + 13 = 3   -->  a₁₄ = 3 - 13   = -10
