last year lien earned 1,700 more than her husband. Together they earned 42,100. howm much did each of them earn?

Answer 1

Let x = the salary of the husband.
So Lien earned x+1700.
Lien's salary + her husband's = 42100
x + 1700 + x = 42100
2x + 1700 = 42100
2x = 40400
x = 20200
Lien's husband earned $20200, and Lien earned 1700 + 20200 = $23900.
