Question
Use an algebraic approach to solve the problem. Find a number such that one-half of the number is 6 less than two-thirds of the number.
Expert Solution
Step 1

Given: 

 One half of the number is 6 less than

 two-thirds of the number.

Find : The value of the number.

Let x be the number.

(1/2)x = (2/3)x - 6

Rearranging  the above terms, 

(x/2) - (2x/3) = - 6  ----------------- (1)

Now we need to  find  a common denominator,  which is 6.

Now equation (1) becomes 

(3x/6) - (4x/6)x = - 6

- x / 6 = - 6

X = 36
