Question 1041921
<pre>
Your equation would be correct if you would place 
parentheses correctly. This is your reasoning,
using {{{TIME=(DISTANCE)/(RATE)}}}

{{{(matrix(7,1,
time,
required,
to,
travel,
matrix(1,2,100,km),
at,
matrix(1,2,x,(km)/(hr))))}}}{{{""-""}}}{{{(matrix(2,1,2.5,hours))}}} {{{""=""}}} {{{(matrix(7,1,
time,
required,
to,
travel,
matrix(1,2,100,km),
at,
matrix(1,2,(x+2),(km)/(hr))))}}}


Not this:

100/x - 2.5 = 100/x+2

But this:

100/x - 2.5 = 100/(x+2)

When typing algebra all on 1 line, if a
numerator or a denominator contains more
than just 1 number, or just 1 letter, you
must type a left parenthesis "(" to indicate
where the numerator or denominator starts,
and a right parenthesis ")" to indicate where
it ends.
