-------------
Consecutive numbers are "x" and "x+1".
EQUATION:
x + x+1 = 71
2x+1 = 71
2x = 70
x = 35
--------------
Hmmmm?
If you have "x" and you add 1 to both sides you get x+1 not 1x
--------------
1x means "one x". It's saying "car"; you mean one car.
Similarly "x" means one x. The "1" is not needed.
