Find the given elements if matrix d:

1274 because the fraction of numbers go flip flop

Element wise subtraction.

Step-by-step explanation:

Matrix Subtraction is done element wise.

Therefore, D = [tex]\[ \left[ {\begin{array}{ccc} 3 & 1 & 0 \\ -1 & 2 & 4 \\9 & 7 & -2 \end{array} } \right]\][/tex] - [tex]\[ \left[ {\begin{array}{ccc} 5 & 2 & -4\\ 1 & 12 & 3 \\ 11 & 3 & -2 \end{array} } \right]\][/tex]

This becomes:

[tex]\[ D = \left[ {\begin{array}{ccc} -2 & -1 & 4 \\ -2 & -10 & 1 \\ -2 & 4 & 0 \end{array} } \right]\][/tex]

Now, [tex]$ d_{11} = -2 $[/tex]

[tex]$ d_{12} = -1 $[/tex]

[tex]$ d_{13} = 4 $[/tex]

[tex]$ d_{21} = -2 $[/tex]

[tex]$ d_{22} = -10 $[/tex]

[tex]$ d_{31} = -2 $[/tex]

income. 10x+1300

expenses 3x+(1800+1500)

expenses 3x+3300

to break even:

income = expense,

10x + 1300 = 3x + 3300,

solve for x.
