Hey!!
Total angle - 180
... 2x + 4 + 2x - 9 + x = 180
... 4x - 5 + x = 180
... 5x - 5 = 180
... 5x = 185
... x = 185 / 5
... x = 37
Hope my answer helps!!
45 of a number refers to 180, and 54 refers to 216. So 100 of a number is 400 and 1 of a number is 4. If 54x - 45x = 36, just plug in 4 and double check: 54(4) - 45(4) = 36 or 216 - 180 = 36, which is true.
