Answer:
A= 429
B= 50
Explanation:
A+B= 479 (take away)
A-B= 379
A-A+B+B= 479-379 (simplify)
2B= 100
I think you know how to do it now..
B=50
A=50+379 ---> 429
This is the substitution method, there are other ways of doing it- and I tried to make this simple. Hope this helped!

<h3><u>Key Concepts for Reflections:</u></h3>
- if (a, b) is reflected on the <em>x-axis</em>, the image is the point <em>(a, -b)</em>
- if (a, b) is reflected on the <em>y-axis</em>, the image is the point <em>(-a, b)</em>
- if (a, b) is reflected on the line<em> y = x</em>, the image is the point <em>(b, a)</em>
- if (a, b) is reflected on the line <em>y = -x</em>, the image is the point <em>(-b, -a)</em>

5(x+3)=3(2x-1)
**distribute
5x+15=6x-3
-5x -5x
**get like term together
15=x-3
+3 +3
**get x alone on one side of the equation
18=x
check your work by replacing the variable x with 18
5(18+3)=3(2·18 -1)
5·21=3·35
105=105 yes!
So, the number you are looking for is 18
2(x - 1) - (3x - 2)
First, simplify brackets. / Your problem should look like: 2(x - 1) - 3x + 2
Second, expand. / Your problem should look like: 2x - 2 - 3x + 2
Third, gather like terms. / Your problem should look like: (2x - 3x) + (-2 + 2)
Fourth, simplify. / Your problem should look like: -x
Answer: -x
