Last year lien earned $1500 more than her husband. Together they earned $37,500. How much did each of them earn?

Suppose line earned $x, the husband earned $ (x+1500)

therefore;

x + (x+1500) = 37500

solving for x we get

x+x+1500=37500

2x+1500=37500

2x=36000

x=36000/2

x=$18000

Therefore lien was earning $18000 and the husband was earning 18000+1500=$19500
