90+x+72+30 = 180. If you add 90+72+30, you get 192. But to get 180 you have to subtract 12. 90+(-12)+72+30 =180 if x is -12
72 + 72 = 144
72+30=102
180

90+x+72+30 = 180. If you add 90+72+30, you get 192. But to get 180 you have to subtract 12. 90+(-12)+72+30 =180 if x is -12
Well, honey, if 72 plus y equals 180, then y must be 108. Simple math, darling. Now go out there and conquer the world with your newfound knowledge.
72 + 72 = 144
To solve this one, subtract 50 from 180 and you'll have your answer.
It is: 126 plus 54 = 180
a + 3a + 5a = 180 9a =180 a = 20
It is: 97+83 = 180
It is: 157+23 = 180
49 + 72 + 68 = 189
72+30=102
87794 + 39357 + 180 + 439 = 127,770
You would formulate this problem X/100 * 150 = 72 and solve for X.
