WORKSHEET: ALGEBRA 3 - SOLUTION EXERCISE 10


10) Jenny and Bob have a combined weight of 78 kilograms. Jenny weighs 51 kilos
less than twice Bobís weight. How much does each one weigh?
x - Bob's weight
2x - 51 - Jenny's weight
x + 2x - 51= 78
x + 2x = 78 + 51
3x = 129
x = 129:3
x = 43

Bob weighs 43 kg
Jenny weighs 35 kg
