@ddog1437 Can you help me plz

Answer 2

multiply the xy vector by the matrix ...

Answer 3

\[x\binom{1}{2}+y\binom{4}{1}=\binom{7}{5}\]

Answer 4

\({\bf \square x+\square y+\square z=a\\
\square x+\square y+\square z=b\\
\square x+\square y+\square z=c}\\ \quad \\
\implies
\begin{bmatrix}
\square &\square &\square \\
\square &\square &\square \\
\square &\square &\square
\end{bmatrix}
\begin{bmatrix}
x\\y\\z
\end{bmatrix}=
\begin{bmatrix}
a\\b\\c
\end{bmatrix}\)

Answer 5

Thank You!
