If 3x - 2y = 8 and x - 4y = 3 , what is the value of x + y ?

33/10 or 3.3

Step-by-step explanation:

3x -2y =8 equ 1

x - 4y = 3 equ 2

from equ 2

2x - 4y = 3

x = 3+4y equ 3

put equ 3 into equ 1

3 (3+4y) - 2y = 8

9 + 12y - 2y = 8

12y - 2y = 8 - 9

10y = -1

y = -1/10

if y =-1/10 then

equ 2

x - 4(-1/10) = 3

x - 4/10 = 3

x = 3 + 4/10

x = 34/10

: .

x + y = -1/10 + 34/10

= 33/10
