James and Lin got married and got new jobs. Lin earns ​$3100 more per year than James. Together they earn ​$81,960. How much does each of them earn per​ year?

Respuesta :

Step-by-step explanation:

We can turn this into an equation.

Let’s denote the amount of money James makes as X.

Then Lin makes X + 3100.

Together they make 81960.

So combine their earning expressions.

X + X + 3100 = 81960

Solve for X

X = 39430

So James makes $39430 since his earnings are demoted by x.

Lin then makes 3100 + 39430, which is $42530.
