Answer:
the bigger number is 42
the smaller number is 10
Step-by-step explanation:
use algebra to denote:
let x be the bigger number
let y be the smaller number
x+2y=62...(1)
3x-y=116...(2)
x=62-2y...(1a)
substitute
3(62-2y)-y=116
186-6y-y=116
-7y=116-186
-7y=-70
y=-70/-7
y=10
therefore x is:
x=62-2(10)
x=62-20
x=42
