[ Step One ] Rewrite 

[ Step Two ] Rewrite Equation

[ Step Three ] Apply Exponent Rule
Note: 

[ Step Four ] Refine

(4*10,000)+(8*1,000)+(2*100)+(4*10)+(3*1)
40,000+8,000+200+40+3=48,243
That is one way. You can also do this using exponential form!
Hope that helps
Answer:
A solution to a system of equations means the point must work in both equations in the system. So, we test the point in both equations. It must be a solution for both to be a solution to the system. Hope this helps.
The answer is x = 2 and y = 3
