Question

Last year lien earned $1100 more than her husband. Together they earned $47,500. How much did each of them earn? Husband earned what?

Answer 1

L=Lien
H=Husband

L+H=$47500
L=H+$1100
plug in L

H+1100+H=47500
2H+1100=47500 (Subtract 1100 to both sides)
2H=46400 (Divide both sides by 2)
H=23200

Now we need to figure out how much alien makes

L+H=47500
L+23200=47500 (Subtract sides by 23200)
L=24300


Lien earned 24300
Her husband earned 23200
