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

are you an artist's daughter? cuz dang you a fine piece of art, girl.

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
