Question 55

Multiple Choice

Find x and y. [x−27y]=[−20−273]\left[ \begin{array} { c c } x & - 2 \\7 & y\end{array} \right] = \left[ \begin{array} { c c } - 20 & - 2 \\7 & 3\end{array} \right]


A) x=20,y=−3x = 20 , y = - 3
B) x=120,y=−13x = \frac { 1 } { 20 } , y = - \frac { 1 } { 3 }
C) x=120,y=13x = \frac { 1 } { 20 } , y = \frac { 1 } { 3 }
D) x=−20,y=3x = - 20 , y = 3
E) x=−120,y=13x = - \frac { 1 } { 20 } , y = \frac { 1 } { 3 }
