When 4 is added to one-half the number x, the result is the same as if 2 had been subtracted from the number x. How do you write an equation that expresses this relationship?
To write the equation expressing this relationship we can take this one phrase at a time:
"one-half the number x" can be written as:
"When 4 is added to" this expression we get:
"the result is the same as" is the same as "=" so we can write:
"if two had been subtracted from the number x" can be written as:
Putting this together gives us our full equation:
