How do you solve these matrices equations?
1. -3x +[7 0 -1] = [10 0 8]
[2 -3 4] [-19 -18 10]
2. -3y + 2[6 9] = [27 -18]
[-12 15] [30 6]
3. 3[2 0]-2x =[-10 5]
[-1 5] [0 17]
4. 5x -[1.5 -3.6] = [0.2 1.3]
[-0.3 2.8] [-5.6 1.7]
I'll just do one. It's just like solving ordinary equations, except you do the operations to all the elements or to corresponding elements: I'll go through every step, but you'll be able to do some of the steps in your head.Subtract the matrix on the left from both sides: Subtract the matrices by subtracting corresponding elements Divide both sides by -3 by dividing every element by -3 Edwin
