Answer provided by our tutors
let 'x' and 'y' be the numbers.
the sum of the numbers is 281
x + y = 281
the second number is equal to 400 decreased by two times the first number
y = 400 - 2x
by solving the system of equations
x + y = 281
y = 400 - 2x
we find
x = 119
y = 162
the numbers are 119 and 162.
