The addition of a number and its consecutive is 81.
n +(x+1)=81
An odd number plus 5 equal 8
(2z+1)+5=8
5x2 +3−2x2 +1=
3x2 +4

n2-n
If you subtract 11 from the number and then treble the result, the answer is 20.
3(x-11)=20
If you multiply the number by 5 and subtract 4, you get the same answer as when you add 3 to the number and then double the result.
