1) x+(x+2)=20
2x+2=20
2x=20-2
2x=18
x=18/2
x=9
2) Winnie=x
Tom=y
David=z
x+(3x)+(4x)=$3,200.00
8x=$3,200.00
x=$3,200.00/8
x=$400.00
Winnie received $400.00
2x+2=20
2x=20-2
2x=18
x=18/2
x=9
2) Winnie=x
Tom=y
David=z
x+(3x)+(4x)=$3,200.00
8x=$3,200.00
x=$3,200.00/8
x=$400.00
Winnie received $400.00

1. Suppose the smaller number is x.
x+x+2=20
2x=18
x=9
2. Suppose Winnie recive $x
Tom recive $3x
David recive $4x
x+3x+4x=3200
8x=3200
x=400
x+x+2=20
2x=18
x=9
2. Suppose Winnie recive $x
Tom recive $3x
David recive $4x
x+3x+4x=3200
8x=3200
x=400
