Final answer:
To write a matrix equation equivalent to the given system, represent the matrices A, X, and B. The matrix equation is [4 -3][x y] = [10 30].
Step-by-step explanation:
To write a matrix equation equivalent to the given system of equations, we can represent the coefficients and constants in matrix form. Let A be the coefficient matrix, X be the variable matrix, and B be the constant matrix. The given system of equations can be written as:
AX = B
Using the coefficients from the given equations, the matrix equation is:
[4 -3][x y] = [10 30]
