Solve for U:
U/5-2.6 = 3.8
Put each term in U/5-2.6 over the common denominator 5: U/5-2.6 = U/5-(13.)/5:
U/5-(13.)/5 = 3.8
U/5-(13.)/5 = (U-13.)/5:
(U-13.)/5 = 3.8
Multiply both sides of (U-13.)/5 = 3.8 by 5:
(5 (U-13.))/5 = 5×3.8
(5 (U-13.))/5 = 5/5×(U-13.) = U-13.:
U-13. = 5×3.8
5×3.8 = 19.:
U-13. = 19.
Add 13. to both sides:
U+(-13.+13.) = 19.+13.
13.-13. = 0:
U = 19.+13.
19.+13. = 32.:
Answer: | U = 32.
