Question

Find x and y.​ $$\left[ \begin{array} { c c c c } 
16 & 4 & 10 & 4 \
- 3 & 13 & 15 & 10 \
0 & 2 & 25 & 0
\end{array} \right] = \left[ \begin{array} { c c c c } 
16 & 4 & 3 x + 4 & 4 \
- 3 & 13 & 15 & 5 x \
0 & 2 & 3 y - 5 & 0
\end{array} \right]$$ ​
A)x = -2,y = 10
B)x = 2,y = -10
C)x = -2,y = -10
D)x = 10,y = 25
E)x = 2,y = 10

Quizplus · Accepted Answer

By comparing the corresponding elements of the matrices, we can solve for x and y. For x, comparing the elements in the first row, third column gives $3x + 4 = 10$, solving this equation gives $x = 2$. For y, comparing the elements in the third row, third column gives $3y - 5 = 25$, solving this equation gives $y = 10$.
