looking for some help to rearrange a formula to make x the subject

2x/5-3b/4=x+5

i moved +5 to the left and it became -5

i thought the negative 5 would cancel the denominator 5

this is what i thought i could do

2x-3b/4=x

-2x -2x

-3b/4 =-x

multiply both sides by -1 and the result i thought should be

3b/4=x

thanks in adv
