Question

if 2x + y= 23 and 4x-y=19 find the value of 5 y-2x and y/x -2

Answer 1

Answer:

20 and -0.714 or -5/7

Step-by-step explanation:

by sloving both the equation we get x=7 and y=9

so 5(y-2x)

=4(9-14)

=4(-5)

=20

and y/x-2

=9/7-2

=1.285-2

= -0.714 or -5/7

Answer 2

Answer:

2x+y=23

4x-y=19

=6x=42

x=7

so, 2(7)+y=23

=y=23-14=9

y=9

=5y-2x=5(9)-2(7)

=45-14

=31

y/x-2= 9/7-2

=9/5

This is the answer
