Question

If a-1=b+2=c-3=d+4, then which is greatest among a,b,c,d

Answer 1

let's take a and related it with others
b=a-3
c=a+2
d=a-5
so,a+2<a<a-3<a-5

Answer 2

a-b = -3
b-c = -5
find a+c by eliminating b
now, a-c= -2
find value of a
if value of a is determined value of b,c and d are determined
find which one is greatest
