Question 364426: Solve the matrix equation
-2x+3■(2&-8@-4&2)=■(4&-6@2&-8)
I am not sure how to type matrices in here.
Please help, I am trying to help my son with his algebra and neither one of us understands how to do this. Could you please explain in step by step instructions. Thank You.

You can put this solution on YOUR website!
You can list them in order, like,
[A] is a 2x2 matrix [A]=(1 2 3 4) for [A]=%28matrix%282%2C2%2C1%2C2%2C3%2C4%29%29
[B] is a 3x3 matrix [B]=(9 8 7 6 5 4 3 2 1) for [B]=%28matrix%283%2C3%2C9%2C8%2C7%2C6%2C5%2C4%2C3%2C2%2C1%29%29
[C] is a 3x1 matrix [C]=(x y z) for [C]=%28matrix%283%2C1%2Cx%2Cy%2Cz%29%29
Then solve,
4[B][C]-12[C]
