after losing 25 pounds an individual weighs 105 pounds more than one third of his previous weight. what is the previous weight ?
2 answers:
X - 25 = 1/3x + 105
x - 1/3x = 105 + 25
2/3x = 130
x = 130 * 3/2
x = 390/2
x = 195 <==== previous weight
X-25 = 105 + 1/3(x)
-1/3(x) - 1/3(x)
2/3(x) - 25 = 105
+ 25 +25
2/3(x) = 130
*3/2 *3/2
x = 195
The individual’s weight before is about 195lb
