You can put this solution on YOUR website! If 1 more than a certain number is 3 less than a second number, the larger of these numbers minus he smaller is equal to:
:
Let x = "a certain number"
Let y = "a second number"

x + 1 = y - 3
x = y - 3 - 1
x = y - 4
we can rewrite this to
y - x = 4
which answers the statement,"the larger of these numbers minus he smaller is equal to"
