Nady [450]
To write the equation, you can start with the answer of $680. She receives $400 + $20*plans sold: 400 + 20p = 680 20p = 280 p = 14 {$400 + $20 * 14 = 680} Sam sold 14 plans to make a total of $680.

8b-ab=7a, .subtracted from 3a-9ab+b<br>​
Tresset [83]

Answer: You can't. Read explanation.

Step-by-step explanation:

You can't subtract an expression from an equation. If you said something like subtract 8b-ab+7a from 3a-9ab+b that would work, but not here.

Let's just assume You mean it as 8b-ab-7a, then (3a-9ab+b)-(8b-ab-7a) = -8ab + 10a - 7b.

Hope that helped,
