9 1/2 = 19/2
(29/5) / (19/2)
When changing division to multiplication, flip the number (right hand side).
(29/5) * (2/19)
58/95
126.4 I guess.... How you wrote it is a tad confusing. Is the second set of numbers another question?
A graphing calculator shows two solutions:
(x, y) =
(-2, 0) or (-1, -10)

Answer:
Number of sent mail = 36
Number of received mail = 75
Step-by-step explanation:
Let,
x be the number of mails sent
y be the number of mails received
According to given statement;
x + y = 111 Eqn 1
y = 2x + 3 Eqn 2
Putting value of y from Eqn 2 in Eqn 1
x + 2x + 3 = 111
3x = 111 - 3
3x = 108
Dividing both sides by 3
Putting x = 36 in Eqn 2
y = 2(36) + 3
y = 72 + 3 = 75
Hence,
Number of sent mail = 36
Number of received mail = 75
