Answer:
11:3
Step-by-step explanation:
For every 11 y there is 3x
Hello :
let : x = s so : y = x-1
all points is the line passe by : (1, 0) of the slope 1
[ 2x + y = -9 ] x -3
[- 3x +11= y ] x 2
-6x -3y = 27
-6x + 22 = 2y
-6x +27 = 3y
-6x +22 = 2y
5 = y
-6x -3x5 = 27
-6x -15 = 27
-6x = 42
-x = 42/6
-x = 7
x = -7
answer
x = -7
y = 5
The answer to this problem is -20
