You can put this solution on YOUR website! .
M=Michelle's age; D=David's age
.
D=M+1
.
2D+(M-3)=44
2(M+1)+M-3=44
2M+2+M-3=44
3M-1=44
3M=45
M=15
ANSWER 1: Michelle is 15.
.
D=M+1=15+1=16
ANSWER 2: David is 16.
.
The results if Michelle is older are not integers.
.
CHECK:
.
2D+(M-3)=44
2(16)+(15-3)=44
32+12=44
44=44
