Solve the matrix equation.

X+[-16]
     [  -9]   + 16  = -29
    [ -12]       9        -29
      [  7 ]     -6       -10
                    1        26

anonymous · Answer

do you mean ...

$$X+\left[\begin{array}{c}
-16\
-9\
-12\
7
\end{array}\right]+\left[\begin{array}{c}
16\
9\
-6\
1
\end{array}\right]=\left[\begin{array}{c}
-29\
-29\
-10\
26
\end{array}\right]$$

anonymous · Answer

yeah, sorry it didn't come out right

anonymous · Answer

$$X=-\left[\begin{array}{c}
-16\
-9\
-12\
7
\end{array}\right]-\left[\begin{array}{c}
16\
9\
-6\
1
\end{array}\right]+\left[\begin{array}{c}
-29\
-29\
-10\
26
\end{array}\right]$$

now just add

anonymous · Answer

what would that come out to

anonymous · Answer

what do you think?

anonymous · Answer

it can't be as simple as adding, -16 + 16 = 0. then what?

zarkon · Answer

-(-16)-16+-29

zarkon · Answer

that would be the first entry of $X$

anonymous · Answer

so the second would be -(-9)-9+-29

anonymous · Answer

@Zarkon

zarkon · Answer

yes

anonymous · Answer

that would come out to -29 and that can't be right.

zarkon · Answer

if that is not correct then make sure you typed the original question correctly
