Question

The sum of two numbers is 49. The sum of the smaller and 2 times the larger is 83. Find the two numbers.

Answer 1

let the small number be x and the big number be y
x+y=49
x+2y=83
by solving simultaneously,
x=15 and y=34

Answer 2

Let the smaller no be x and the larger no be y.So according to given conditions,
x+y=49--------(1)
x+2y=83-------(2)
subtracting eq2 from eq1, we get
y=34.put in eq.1, we get x=15, so the two numbers are 15 and 34.
