Show equation AX=B represents a linear system of two equations in two unknowns. Solve the system and substitute into the matrix equation to check results. I have no idea can you help me out


A=|1,2|
|-3,5|,

X=|x[1]x[2]|,

B=|-4 12|

  • Algebra -

    The matrix equation AX=B results in the system of equations
    x1 + 2x2 = -4
    -3x1 + 5x2 = 12

    I am sure you can solve that.
