Justin weighs 15 pounds less than greg weighs. half of greg’s weight is 75 pounds less than justin’s weight. how much does each of them weigh?

Justin=JGreg=G
Information we have:J+15=GG/2=J-75
Since J+15=GJ = G-15We now replace J in the second equationG/2=(G-15)-75G/2=G-90G=(G-90)*2G=2G-180G-2G=-180-G=-180G=180
Greg = 180 poundsJustin = 165 pounds
