u take x then multiply it by b, the add 9 to x then we will get the answer xb9x, hope u understand;>
Answer:

Step-by-step explanation:
When we solve for an equation, our goal is to find the value of the variable. Any variable can be used, but for the time being let’s assume we use
.
We can algebraeically solve equations until we get the value of x - in which we will have x equal to something.
Say we have the equation
. Our goal is to find the value of
. <u>We can do this by getting x isolated on one side so we have something equal to x</u>.
We can subtract 5 from both sides and divide both sides by 5.

We now know the value of
since it’s on one side of the equation.
Hope this helped!
What do you wanna know?
The annual interest rate is 2000•0,05=100
The new price you have to pay is 2000•1.05 (change factor)
I believe the answer is A because the formula for area is length times width.
