Make x the subject of the formula y=2x-3​

The questions is basically saying make x isolated.

First add 3 to both sides.

y+3=2x-3+3

y+3=2x

Now divide both sides by 2

(y+3)/2=x

x=(y+3)/2

Done!

Any questions just ask me in the comments.

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.
