If x is 1, then 23x is 23, so we have 23-1=22 as the answer.
Two vector spaces V and W are said to be isomorphic if there exists an invertible linear transformation (aka an isomorphism) T from V to W.
Consecutive integers area 1 apart
they are
x,x+1,x+2
sum is
x+x+1+x+2=87
3x+3=87
minus 3 both sides
3x=84
divide both sides by 3
x=28
x+1=29
x+2=30
the smallest number is 28
The answer to your question is 30 units.
Hope this helps! :D
