Question 1073435
let x, y be the two numbers with x < y
:
1) x + y = 40
2) y + 2 = 2x
:
solve equation 1 for y
:
y = 40 - x
:
substitute for y in equation 2
:
40 - x + 2 = 2x
:
3x = 42
:
x = 14
:
y = 40 - 14 = 26
:
************************************
the two numbers are 14 and 26
:
check the answer
:
14 + 26 = 40
:
26 + 2 = 2 * 14
:
28 = 28
:
our answer checks
