Answer:
x = 4.4
Step-by-step explanation:
I'm going to assume you want to solve for x so here we go.
You need to work backwards for this equation, and whatever you do to the LHS, you do to the RHS.
First, you need to remove the minus 3, which means that on both sides, you add 3. Adding three on the LHS makes the -3 disappear, and adding 3 on the RHS makes the 19 go to a 22. 
Your equation is now 5x=22.
Since 5x means 5 × x, to get rid of it, you need to divide 5x by 5. Doing it to the LHS will make the five disappear, and doing it to the RHS will make it go to 22 ÷ 5 which equals 4.4
Therefore, x = 4.4

Hi!
So really focus on the fact that he started at $230, and then added an amount of money which we'll call x, which made his total equal $599. 
Take the parts I put in bold, and write the equation.
$230 + x = $599
Now we need to find x. 
Whatever we do to the equation, we do it to both sides. 
Our goal is to isolate x on one side. 
Subtract 230 from both sides. 
$230 - $230 + x = $599 - $230
x = $369
The answer is A. $230 + x = $599 x = $369
Hope this helps! :)

Answer:
Step-by-step explanation:
the  expression could help you find the distance between A(x; y) and B(x',y')is:
AB = √((x-x')²+(y-y')²)
in this exercise  :  x = 10
                              x' = - 6
                               y =4
                              y' = 4
