Step by Step Solution

Step 1 – Description of step.

As the matrices are equal, the corresponding elements are equal. Write the two linear equations to show this equality.


Step 2 – Description of step.

Multiply x-3y=13 by 2 and subtract 2x+y=5 from the obtained equation.


Step 3 – Description of step.

Divide each side of -7y=21 by -7 to find the value of y.


Step 4 – Description of step.

Substitute -3 for y into x-3y=13 and simplify to find the value of x.


Step 5 – Description of step.

Subtract 9 from both the sides of x+9=13 and simplify.


Therefore, the solution is 4,-3.
