BD = 2 AE
10 x + 2 = 2 * ( 3 x + 5 )
10 x + 2 = 6 x + 10
10 x - 6 x = 10 - 2
4 x = 8
x = 8 : 4
x = 2
And the line AC is equal to BD.
AC = 10 * 2 + 2 = 20 + 2 = 22
Answer:
3.  22

Abby rode the Metro bus 4 miles farther than James rode. The sum of their distances traveled is 28 miles. How far did James ride
ohaa [14]
A. define the variables : a = abby's miles, j = james' miles

b. a = j + 4......j = a - 4

c. a + j = 28
    a = j + 4
    
 d. (j + 4) + j = 28
      2j + 4 = 28
      2j = 28 - 4
      2j = 24
       j = 24/2
       j = 12
  
       a = j + 4
       a = 12 + 4
       a = 16

e. check..
     a + j = 28
     16 + 12 = 28
      28 = 28 (correct)

solution is : abby's miles (a) = 16
                   james' miles (j) = 12
