Stephanie has d dollars to invest and splits the money between two accounts. If she invests $ 3100 in one​ account, write an algebraic expression in terms of d for the amount she invests in the second account.

second account = d - 3100

(8k+k² -6)-(-10k+7-2k²)

Let x be the amount Stephanie invests in the second account.

Since Stephanie splits her money between two accounts and invests $3100 in one account, the amount she invests in the second account can be expressed as:

d - $3100 = x

Let's break down the given information:

Stephanie has d dollars to invest.
She invests $3100 in one account.

To find out the amount she invests in the second account, we need to subtract $3100 from the total amount d that she has to invest. This can be represented as an algebraic expression.

Let's call the amount Stephanie invests in the second account x dollars. Since she already invested $3100 in the first account, the equation to represent the amount she invests in the second account would be:

x = d - 3100

So, the algebraic expression in terms of d for the amount Stephanie invests in the second account is: d - 3100.
