Answer:
y = 30.555 and x = 19.444
Step-by-step explanation:
We are given:
x + y = 50 and
x / y = 7/11
use substitution taking
x + y = 50
x = 50 - y
then
x / y = 7/11 and from above substitute for x
(50 - y)/ y = 7/11
(50 - y) = 7y/11
11(50 - y) = 7y
550 - 11y = 7y
550 = 18y
y = 550/18 = 30.555 so
x + y = 50
x = 50 - y
x = 50 - 30.555 = 19.444
