HELP ASAP PLSSS PLSPLSPLS

Tom and Tammy each opened a savings account today. Tom opened his account with a starting amount of $490, and he is going to put in $70 per month. Tammy opened her account with a starting amount of $670, and she is going to put in $40 per month.
Let x be the number of months after today.

Write an equation to show when the two accounts would have the same amount of money.

Answer:

490+70x=670+40x

Explanation:

This is almost exactly the same as the pizza/giftcard question. But here Tom and Tammy are saving money, so ADD the monthly amount. 70x for Tom and 40x for Tammy.

Tom's account:

490 + 70x

Tammy's account:

670 + 40x

When they say "when the two accounts have the same amount of money" SET them EQUAL to each other.

490+70x=670+40x
