Answer:
14
Step-by-step explanation:
2x + y = 20 (1)
2x + 3y = 36 (2)
(2) - (1) ⇔ (2x - 3y) - (2x + y) = 36 - 20
⇔ 2y = 16
⇔ y = 8 (3)
From (3) and (1), we have:
2x + y = 2x + 8 = 20
⇔ 2x = 12
⇔ x = 6
So: C = x + y = 6 + 8 = 14
Conclusion : C = 14

Find the least common denominator for each of these fractions then complete the equation until it equals 1.
Common factor is 30
u/5 = 6u/30
u/10 = 3u/30
-u/6 = -5u/30
6u/30 + 3u/30 - 5u/30 = 1
4u/30 = 1
4u = 30
u = 7.5
