Just use the coefficients for each variable and put it in a matrix. Is the second question set equal to something? Because then you would put it in place as the question mark. (Did the pic come through?)
So the 3x3 matrix is made up of the coefficients and then to augment the matrix, you add another column at the end with the solutions. Good luck!

- ➣ Circle:- A two-dimensional geometric figure, a line, consisting of the set of all those points in a plane that are equally distant from a given point (center).
- ➣ Circumference:- The line that bounds a circle or other two-dimensional figure

★ also circumference of a circle is also known as it's perimeter
- ➣To find circumference of circle when use formula

- ➢ r = radius (25inch.)
- ➢ value of π is 3.14



★ Hence circumference of circle=157inch


Hope it helps !
