Suppose he invest x dollars in one account, y in the other
x+y=12,500
0.042x+0.062y=669.50
multiple the first equation by 0.042: 0.042x+0.042y=525
subtract this new equation from equation 2: 0.02y=144.50
y=7225
x=12500-7225=5275

This is a statement not a question.
Answer:
It's C. (x=-4, y=7, z=2)
Step-by-step explanation:
It's C, because:
4(-4) +2(7) +5(2)=8 <----- (4x+2y+5z=8)
5(-4) +3(7) +4(2)=9 <------ (5x+3y+4z=9)
6(-4)+3(7)+3(2)=3 <------ (6x+3y+3z=3)
