The system of linear equations -2y+ y = 8 and -3x -y=7 is graphed below. What is the solution to the system of equations?
2 answers:
Answer:
x=1/3 y= -8
step explanation:
-2y+y= 8 then -y=8 y= -8
-3x-(-8) =7
-3x +8 =7
-3x=-1
x=1/3 y= -8
Answer:
x= 1/3
y = -8
Step-by-step explanation:
-2y+ y = 8 equation 1
-3x -y =7 equation 2
using equation 1 we have:
-2y+ y = 8
-y = 8
y = -8 equation 3
using equation 3 in equation 2 we have:
-3x -y=7
-3x -(-8)=7
-3x +8 =7
-3x = 7-8
-3x = -1
x= 1/3

Have a nice day :)
Id say 40%
because 8 are math so 9 of them are other
3/2 = 6
6/4= 6/40= 6 .999= ~ 7
Answer:
(2,-2) --> (-1, 3)
(8,-2) --> (5, 3)
(8,-5) --> (5, 0)
(2,-5) --> (-1, 0)
