Answer:
x = 65
y = 32
Explanation:
2x + (x - 15) = 180
2x + x - 15
3x - 15 = 180
+15 +15
-------------------
3x = 195
÷3 ÷3
----------------
x = 65
4y + (y + 20) = 180
4y + y + 20 =180
5y + 20 = 180
-20 -20
---------------------
5y = 160
÷5 ÷5
---------------
y = 32
2x + (x - 15) + 4y + (y + 20) = 360
2(65) + (65 - 15) + 4(32) + (32 + 20) = 360
130 + 50 + 128 + 52 = 360
180 + 180 = 360
360 = 360
I hope this helps!
