You can put this solution on YOUR website!
Their current ages are x and x^2.
In 7 years, their ages will be x+7 and x^2+7.
Write and solve the equation that says
"Nancy's age 7 years from now is (will be) equal to 1 more than 2 times Paeng's age then"
This will be a quadratic equation with two solutions, one of which is negative. Of course, since ages are positive numbers, you need to choose the positive solution.
