Well, you may do the equation 5x=10 and x would equal 2. Two times Five equals ten/ It is called an algerbraic expression.
3 + x/7 Normally an expression like this forms part of an equation such as y = 3 + x/7
It's not an equation - there's no "is" or "equals." You can write it as a mathematical *expression*, however:140 "decreased by 20%"140 - (20/100)*140
