Question 718042: The weight of two pieces of baggage is 38 kg. If the weight of one is 7 kg less than twice the weight of the other. What is the weight of each piece of baggage? Answer by algebrahouse.com(1659) (Show Source):
x + 2x - 7 = 38 {the combined weight of the two is 38}
3x - 7 = 38 {combined like terms}
3x = 45 {added 7 to each side}
x = 15 {divided each side by 3}
2x - 7 = 23 {substituted 23, in for x, into 2x - 7}
