Solve for x:
(5 x)/2+19 = 34

Put each term in (5 x)/2+19 over the common denominator 2: (5 x)/2+19  =  (5 x)/2+38/2:
(5 x)/2+38/2 = 34

(5 x)/2+38/2 = (5 x+38)/2:
(5 x+38)/2 = 34

Multiply both sides of (5 x+38)/2 = 34 by 2:
(2 (5 x+38))/2 = 2×34

(2 (5 x+38))/2 = 2/2×(5 x+38) = 5 x+38:
5 x+38 = 2×34

2×34  =  68:
Answer: | 
| 5 x+38 = 68
