Answer:
x = [-1 | 5, 2 | 1]
Step-by-step explanation:
We assume your notation is used to describe 2×2 matrices.
Solve for x:
2x -k = m
2x = m + k . . . . add k
x = (1/2)(m +k) . . . . multiply by 1/2
Fill in the values:
x = 1/2[2+(-4) | 8 +2, -2+6 | 5+(-3)]
x = [-1 | 5, 2 | 1]
Let x be the money he had originally.
x/3+5=x/2
5=x/6
x=30
So he had $30 originally.
