A number "m" plus 40 equals 60. Therefore, 60 minus 40 equals m. m therefore equals 20.
54(x)+52+32(y)+72=212
-6x+72=x then -7x=-72 so x=72/7
(5,7)
42 72
89
72 + 72 = 144
60 + 12 = 72
300 !
180+72=252
72+30=102
49 + 72 + 68 = 189
You would formulate this problem X/100 * 150 = 72 and solve for X.

There are 60 minutes per hour: 72 x 60 = 4,320 minutes.
2t - 12 - 3t = 60 -1t - 12 = 60 -1t -12 +12 = 60 + 12 -1t = 72 t = -72
