Answer:

15/2 or 7.5

Step-by-step explanation:

5/6 (x + 1/2 + 4)

distribute 5/6 to each number

5/6x + 5/12 + 10/3

change the fraction 10/3 so that it will have the same denominator as 5/12

\frac{10}{3} *4 = 40/12

5/6x + 5/12 + 40/12\\5/6x + 45/12

divide both sides by 5/6

x = 9/2

5/6*9/2+5/12+10/3 = \frac{15}{2}
