What is the value of x in the equation (x-5)/2 + 7 = 28. Show how you get your answer.
The first step is to subtract 7 from each side to obtain (x-5)/2 = 21. Then, multiply each side by 2 to get rid of the fraction on the left side: x-5 = 42. The final step is to add 5 to each side to get the value of x: x = 47.
