    Answer:

    [row 1, row 2] [0 1, 4 -5] col [x y] = col [ 10 3]

    Step-by-step explanation:

    Given the system of equation:

    y = 10

    4x – 5y = 3

    The matrix that will represent this set of equation will be a 2×2 matrix because of the amount of unknown variables which is 2 (i.e x and y)

    Looking at the first equation, there are no variables x but thwore is a variable y with a coefficient of 1

    The first row of the 2×2 matrices will be represented by the coefficient of the variables

    For the left hand of the first equation, the resulting row matrix is [0 1]

    Similarly for the left hand of the second equation, the resulting row matrix is [4 -5]

    The unknown variables and their resulting values will both form a column matrix each. col [x y] and [10 3]

    Combining the matrices we have;

    [row 1, row 2] [0 1, 4 -5] col [x y] = col [ 10 3]
