Example Question #213 : Number Manipulation*
If twenty is subtracted from a number, the difference is equal to the same number divided by two. What is this number?
If we let be the number in question, "twenty...subtracted from a number" can be rewritten as ; "the same number divided by two" can be rewritten as . The two are equal, so we solve the equation
One way to solve this is to first multiply both sides by two to eliminate the fraction:
Distribute:
Subtract from, and add 40 to, both sides:
.
