Answer: Lets call the number x
decreased means subtraction. If x is decreased bt 23% then the result is
x-23%(x) = x-(23/100)x or x-.23x
x-.23x=539
.77x=539
x=539/.77
x=700
check: 700-.23(700)=539
700-161=539
539=539
Our answer is correct

X --- <span>first number
y --- </span><span>second number
x + y = 2x - 15
x - y = 2y - 5
x - 2x + y = -15
x - y - 2y = - 5
-x + y = -15
x - 3y = - 5
-----------------
-2y = -20 /:(-2)
y = 10
</span>x - 3y = - 5 ⇒ x = - 5 + 3y = - 5 + 3 · 10 = - 5 + 30 = 25
Ans.:
x = 25
y = 10
