Answer:
Step-by-step explanation:
The ratio of copies printed is ...
X : Y = 1 : 2
so the ratio of the number printed by machine X to the total is ...
X : (X+Y) = 1 : (1+2) = 1 : 3
1/3 of the 159 copies were printed by machine X, so it printed ...
(159)(1/3) = 53
Twice that many were printed by machine Y, so it printed ...
2·53 = 106
Machine X printed 53 copies; machine Y printed 106 copies.

Answer:
a = 12
Step-by-step explanation:
a+b+c+a+c+b+a+c = 12+a+a+b+b+c+c+c
=> 3a + 2b + 3c = 12 + 2a + 2b + 3c
=> 3a - 2a + 2b - 2b + 3c - 3c = 12
=> a = 12
