x-(2x\7)=5
((7x-2x)\7)=5

division opp. multiplication

x=7
Answer by josmiceli(19441) (Show Source): You can put this solution on YOUR website!

there are several ways you could have written the left side of
this equation, and their all equal to eachother.

notice that the 7 stays below the fraction line in each case
and all I'm doing is changing the order of x and 2.
To solve any equation, just do the same thing to both sides
at each step. The "=" sign is the balence point and you're keeping
both sides balenced.
multiply both sides by 7

you can rewrite the left side as follows

7/7 = 1 (anything divided by itself is 1.
1*(2x) is the same as 2x

multiply out the right side

divide both sides by 2

2/2 is 1 and 1*x is the same as x.
is the answer (or 17 1/2 if you like)
