Let's solve for x.
Layout equation:
a/b
(2x−12)=c/d
Step 1: Multiply both sides by b.
2ax−12a=bc/d
Step 2: Multiply both sides by d.
2adx−12ad=bc
Step 3: Add 12ad to both sides.
2adx−12ad+12ad=bc+12ad
2adx=12ad+bc
Step 4: Divide both sides by 2ad.
2adx/2ad=12ad+bc/2ad
So the answer is x=12ad+bc/2ad.
