how do you Solve: |4x 3y| = |-12 15|

Question

How do you solve the question, step by step

Answer 1

Cassie, the matrices you have here are equal, so what you have in each place in one should be equal to what is in the corresponding place in the other. 

 

So, 4x = -12 and 3y = 15.

 

I think you can solve it from here!
