Your answer is 26,453
Although I don't feel as if this is a homework question, I will still show the work.
Work:
Step 1: 999 + 999 = 1,998
Step 2: 1,998 + 999 = 2,997
Step 3: 2,997 + 23,456 = 26,453
Hope I was able to help! :)
A square is a square a trapezoid is a lot weirder <span />
The answer is ..........2/3
Solve both equations for y:
![x-y=3 \ \ \ |-x \\ -y=-x+3 \ \ \ |\times (-1) \\ y=x-3 \\ \\ ay+3a=0 \ \ \ |-3a \\ ay=-3a \ \ \ |\div a, a \not= 0 \\ y=-3](https://tex.z-dn.net/?f=x-y%3D3%20%5C%20%5C%20%5C%20%7C-x%20%5C%5C%0A-y%3D-x%2B3%20%5C%20%5C%20%5C%20%7C%5Ctimes%20%28-1%29%20%5C%5C%0Ay%3Dx-3%20%5C%5C%20%5C%5C%0Aay%2B3a%3D0%20%5C%20%5C%20%5C%20%7C-3a%20%5C%5C%0Aay%3D-3a%20%5C%20%5C%20%5C%20%7C%5Cdiv%20a%2C%20a%20%5Cnot%3D%200%20%5C%5C%0Ay%3D-3)
Set the expressions equal to each other:
![y=y \\ x-3=-3 \ \ \ |+3 \\ x=0 \\ \\ (x,y)=(0,-3)](https://tex.z-dn.net/?f=y%3Dy%20%5C%5C%20x-3%3D-3%20%5C%20%5C%20%5C%20%7C%2B3%20%5C%5C%0Ax%3D0%20%5C%5C%20%5C%5C%0A%28x%2Cy%29%3D%280%2C-3%29)
So, for every nonzero number a the system of equations has
one solution.
