Answer:
At first, we have 3 expressions that are equal.
![3(2+7) - 9 \cdot 7= 3+8 \cdot 2 \cdot 2 - 4](https://tex.z-dn.net/?f=3%282%2B7%29%20-%209%20%5Ccdot%207%3D%203%2B8%20%5Ccdot%202%20%5Ccdot%202%20-%204)
![6+21 - 63= 3+32 - 4](https://tex.z-dn.net/?f=6%2B21%20-%2063%3D%203%2B32%20-%204)
![-36=31](https://tex.z-dn.net/?f=-36%3D31)
![-36\neq 31](https://tex.z-dn.net/?f=-36%5Cneq%2031)

Answer:
X= 43
y=120
Step-by-step explanation:
3x + 8 + X = 180
4x = 180 - 8
X = 43
2y +17+X = 180
2y + 17 + 43 = 180
y = 180 - 60
= 120
