|2x-3|=2 please answer this by Wednesday. I have no idea how to solve this. I wasn't paying attention

Ok so in order to solve you need to get the variable by itself, in this case it is x. The first thing you do is add or subtract. You add 3 to the left side to cancel it and whatever is done to one side must be done to the other which is why you add 3 to 2. Now the equation is 2x=5. In order to get the x by itself you must divide by 2. When you divide 2x by 2, the 2 will cancel out. Again, you have to do the same thing to the other side. 5 divided by 2 is 5/2, so x=5/2 is your answer. To check, plug in 5/2 for x. 2 times 5/2 is 5 and 5-3 is 2. 2=2 so the answer is correct. Hope this helped!

Answer:
p(x) = 0.85x
t(x) = 1.065x
(t o p)(x) = 0.9x
$2700
Step-by-step explanation:
If the marked price is $x, then the function p(x) that gives the price of the riding lawn mower after 15% discount will be
where x is the marked price.
Now, the function that gives the total cost with sales tax will be given by
where x is the discounted price.
Therefore, the composite function that gives the total cost of the riding lawn mower on sale is given by
(t o p)(x) = 1.065(0.85x) = 0.9x ............ (1)
where x is the marked price.
If the marked price x = $3000, then Mr. Rivera has to pay for the riding lawn mower, from equation (1),
(t o p)(3000) = 0.9 × 3000 = 2700 dollars. (Answer)
