How do you solve this equation x over 9 equals 12?
x/9=12 multiply both sides by 9, giving x=108 ____________________________________________________________________ To solve the problem 'x over nine equals twelve', you must first recognize that any number over another number (which includes variables) is a division problem. Thus, all fractions are division problems. You have to multiply by the reciprocal, and multiplication is the opposite of division, and the reciprocal in this case would be 9/1, or just 9. You must apply this to both sides of the equation, so x/9 times 9 is x, and 12 times 9 is 108. Therefore, x =108.
