Answer:
x= -10
y= -4
Step-by-step explanation:
Given data
3x+1=8y----------------1
11y-3x=-11--------------2
rearange
3x-8y=-1------------------1
-3x+11y=-11---------------2
add 1 and 2
3x-8y=-1------------------1
-3x+11y=-11---------------2
0+ 3y= -12
y= -12/3
y= -4
put y= -4 in 2
11y-3x=-11
11(-4)-3x=-11
-44-3x=-11
-44+11=3x
-33= 3x
x= -33/3
x= -10
