Solve for x in the following matrix equation.
[5x-8 1] = [2 1]
[3 4m-1] [3 7m+6]

How do you do this? I hardly know anything about this... The packet I got that was supposed to help me understand matrices and stuff just made me more confused.

  • Algebra -

    each element must be identical in the two matrices (you already have 1=1 and 3=3), so you just have to solve

    5x-8 = 2
    4m-1 = 7m+6

    then use those values to fill in the unknown elements.
